Why Cable Termination is Important for Facilities

Cable Termination refers to the “connector” of the wire, fiber, or cables to a device or an outlet. It’s a component that allows the cable to be connected to other cables or devices. A bridge by which the connection is made possible between the cable and junction, a gap closer of some sort. Cable Termination is mostly used in Energy, Telecom, Datacom, and Fiber Optic Industries. You’ve likely imagined already what it’s like in the facilities these industries operate in, that they’re full of meters-long cables going to one place to another. If your earphones can get tangled on its own inside your pockets for just being in there for a few minutes, imagine chaotic it could be in a facility with years-worth of cables being installed.

Cable Management

Cable Management refers to proper inventory and organization of electrical and optical cables in cabinets or installations.  The major pain point which the practice seeks to solve is “cable spaghetti”. Cables can get tangled easily, making them hard to work with. This may result in devices being accidentally unplugged when attempting to move another. This also gets in the way of problem diagnosis and future hardware updates. Professionally done cable management allows for smooth operations and system maintenance.

Clutter-Free Facilities

Some good practices for an organized and clutter-free facilities are as follows:

Prioritize cabling when planning for network expansion:

It’s easy to see the difference between a planned and unplanned network just by looking at how cables are laid out. Unplanned network expansion involve a lot of new equipment that are randomly acquired, that causes crisscross of wires and then turns into cable spaghetti. Careful planning of your network helps you position existing and future equipment in ways that they do not overlap.

Over-Estimate Conduit:

Conduits are cable organizers like pipes, and are one of the best ways to prevent entanglement of your network wiring. If you install conduits to only cover your current needs, then you’re bound to face a spaghetti situation in the future when the time comes to add new wires into conduits that are in full-capacity. Get conduits that give you allowance and space for future-use. Cable Termination refers to “connectors” between cables and devices or other cables. They are a crucial part of any electrical facility. Keep a healthy and organized facility with careful planning and by avoiding shortcuts.

How Can Infrared Scanning Help In Substation Maintenance?

Aging infrastructure in power distribution grids are at risk of causing blackouts and brownouts in their respective regions. One of the contributing factors for this is the lack of an automated thermal detection system that exposes critical problems at substations, such as transformer fluid leaks or internal insulation breakdown, which in turn cascades to overheating and a series of failures. This can cause massive problems at banking facilities, security systems, manufacturing plants, food refrigeration, communication networks, and traffic control systems. Repairs and other preparations to get electric facilities up and running again will incur considerable cost and time, luckily there’s a way to save from ever encountering challenges of this degree.

Where it all started

In the mid to late 1980s, utility companies first began using infrared scanning inspection to monitor condition of their substations. But it was only in the early 1990s when this practice achieved remarkable results due to improvements in camera technology and increased resolution provided by the focal plane array.

Revealing the unseen

Saying that substation maintenance is tedious and dangerous work is an understatement. Substations are vast machineries, and they are typically made up of thousands of bolted, crimped, and sliding connections and contacts.  There’s no room for errors in keeping critical components in good working condition, such as lighting arresters, transformers, oil-filled circuit breakers, capacitor banks, voltage regulators, control cabinets, and battery rooms.

It’s a good thing that infrared scanning is such a remarkably effective method for substation maintenance, mainly because it’s non-invasive. Thermographers get readings by capturing several thermal images during an aerial survey on the facility. Readings are achieved even when the facility is operating at peak load. Since this method relies on thermal images instead of manual ocular inspection, safety risks and misreadings are minimized

Worth the trouble

In the field of substation maintenance, infrared scanning is still a method that’s widely used today. Putting effort in inspection work more than pays for itself. In addition to preventing outages, this help keep maintenance staff safe and puts you in good position to avoid any unnecessary costs.

The Importance of Substation Maintenance

If your organization runs with the support of a substation, periodic maintenance will be definitely required. Much like with cars or any motor vehicle, a range of problems can affect your substation after a point in time, especially in terms of reliability and performance. If these issues are overlooked, you may end up facing breakdowns and even safety issues, which aren’t only expensive, but can be dangerous for people.

Substations are the most important part of any electrical generation, transmission, and distribution system. Substations may include transformers to alter voltage levels between high transmission voltages and lower transmission voltages, or somewhere in between of two different transmission voltages. Generally, substation are unattended and remotely supervised and controlled.

Substation maintenance is a process of periodic and planned inspection, repair, and replacement of all switchgears, structures, and ancillary equipment in substation installations. In other words, substation maintenance is routine preventative checks and actions carried out to ensure substations are kept in good working order. The typical process involves a series of strict visual and physical inspections and actions carried out in clusters.

Primary Testing

Circuit breakers and transformers are some of the most important components in a substation. These components experience wear and tear with time and continuous use, hence regular maintenance is done to prevent any malfunctions. Circuit breakers are tested and analyzed to identify the possibility of anomalous operations. Some of the parameters to be checked are poles synchronism, open and close timing, coil condition, and contact resistance. Another thing to look at are the transformers since they play a critical role in substation operations. Transformers tend to experience tremendous thermal stress, hence the need for regular testing too.

Secondary Testing

A secondary test is conducted as a “safety” to the primary test. The objective is to ensure that the established protection scheme delivers. Areas for assessment for the secondary test are relays, wiring, and protection panels.  Overcurrent testing, distant testing, frequency testing, voltage protections, and reclose schemes are also looked into. To recap, much like any other machinery, substations require periodic maintenance to keep it healthy and in good working condition. Substation maintenance involves visual and physical inspections that’s done in two phases. These inspections ensure that wear-and-tear components of the substation are taken care of, and that operations will run smoothly.

Importance Of Electrical Safety In Your Facility

While many people pay little attention to it, electrical safety in the workplace is important because of the many types of hazards that could set off some serious damage when left neglected. The subject at hand should be of high priority for any organization, taking into consideration the figures below.

  • In the U.S, 97% of professional electricians who participated in a survey reported that they have been shocked at least once in the span of their careers. While they’ve only suffered minor injuries, what’s worrying here is the how often this takes place.
  • Electrocution ranks as the 4th most common cause of workplace deaths.
  • In the U.S, around 3,600 people are rendered disabled because of workplace electrocutions.

Human lives are at stake, and there’s high damage to property that would leave your organization crippled if electrical hazards are ignored. Let’s stay safe with these few tips.

Avoid overloading outlets

Electrical outlets are designed to only deliver a certain amount of electricity. Plugging in too much devices in an outlet at once will eventually start a fire.

Avoid extension cords as much as possible

There are those times when you have extra devices that you need to plug in, but as mentioned above, this is a disaster waiting to happen. Have your electrician install new outlet instead for better safety.

Replace or repair damaged power cords

If you see the protective coating on a wire being stripped away, be sure to replace it or at least cover it with electrical tape as soon as possible.

Keep electrical equipment away from water

This one’s a no brainer, yet often overlooked. Water is a conducted and the slightest exposure can lead to injury. Wipe up any spills that are near plugs or electrical devices to avoid trouble.

Install proper physical barriers around electrical hazards

Warning signs may not be enough from preventing people from touching dangerous electrical panels, or going in places where they can come into contact with exposed wires. That’s why it’s more prudent to restrict these areas by installing doors and cabinets around them.

Allow only trained personnel to work on live wires

Any live electrical hazard should only be handled and managed by trained personnel. If you ever see one, it’s best to notify safety personnel who would then place barriers around the hazard.

Importance of a Lightning Protection System

Lightning is one of nature’s most lethal phenomena. It’s a giant discharge of electricity that’s accompanied by a blinding flash of light and a loud roar of thunder. The odds of being struck by lightning in your lifetime is 1 in 3,000, but needless to say, its effects will be devastating. Lightning contains a hundred million electrical volts. It can cause cardiac arrest, severe burns, permanent brain damage or memory loss, and personality change. People can stay safe from lightning by staying indoors, but structures too aren’t immune from its effects.


We’ve all heard about lightning causing devastating damage to structures more than once. There are three hazard categories that helps put things into perspective.

-Fire Hazard

The biggest and most common danger lightning poses to structures is fire. Exposed lightning channels can easily ignite wood and any other flammable materials within the building upon contact with extreme heat. Fire will spread to affected circuits of wires too.

-Power Surge Hazard

The explosive surge of lightning current will do significant damage to any electronic gadget or appliance plugged in.

-Shockwave Damage

Thunder is created by shockwaves that are created by lightning strikes. At close range, these can be destructive, and will easily fracture or destroy hard materials like concrete, bricks, cincerblock, and stone.

Lightning Protection System Defined

A lightning protection system is an upgrade added to structures to safely minimize potential damage caused by lightning strikes. It simply works by providing the heavy electrical charge a path with least resistance to the ground where it is dispersed. A lightning protection system consists of both external and internal elements. External lightning protection system

When Kingkong climbed the Empire State Building, he held on to a tall metal rod at the top. That tall metal rod happens to be a good example of an external lightning protection system equipment called a “lightning rod”, which is used for absorbing and redirecting the overwhelming electrical power. On the other hand, internal lightning protection components are usually used for surge protection. Both keeps people and properties safe from lightning damage.

Cirprotec nimbus® Lightning Rod

A good example of a lightning rod is the nimbus® lightning rod (series of new generation lightning rods with electronic early streaming emission (ESE) by Cirprotec). It has a radius of protection up to 100 m (based on emission times of 15 μs, 30 μs, 45 μs and 60 μs). Complies with standards NF C 17 102:2011, UNE 21186:2011, CTE SU 8.

  • ESE electronic technology, unlike passive Faradization systems with air terminals, makes active use of atmospheric gradient to generate ionization in order to increase the height of the lightning impact point above the tip of the rod, thus increasing the volume protected. This facilitates the protection of large areas, simplifying and reducing material and installation costs.
  • nimbus® has evolved from our successful and reliable range of Nimbus CPT lightning rods, which protect more than 30,000 installations worldwide, a fact that bears witness to its performance, quality and warranty and our service.
  • The new nimbus® lightning rods exceed the requirements of the new version of standard NF C 17-102 v2011, with the goal of making them more robust, without sacrificing their compact size and with a significant weight reduction.

Upgrading your home or corporate property to be lightning-proof may cost you, but the rewards will definitely be worth it when this natural phenomenon starts to pose a threat.

Electric Vehicles As Tools Against Climate Change

Climate change is real and it has caused considerable damage to man and the environment, and will continue to do so in the future if no substantive steps are made.

Climate change’s true terror in the Philippines

According to the Global Climate Risk Index in 2015, the Philippines is the number one most affected country by climate change. While development efforts and geography are also factors that contribute to its high ranking, it’s hard to deny the degree of influence climate change plays here. The Philippines is situated in the western part of the Pacific Ocean and is surrounded by naturally warm waters. As our planet continues to heat up, average sea-surface temperatures continue to rise, and the hotter the ocean and air gets, the more frequent and violent the typhoons are. This is exactly what we’ve seen in the Philippines over the last decade, as five of the ten deadliest typhoons made landfall here.

Individual efforts against climate change

While there’s a lot of movements going on globally to fight climate change, it’s always a great thing to make our individual contribution in saving our planet, and one of them is by owning an electric vehicle.

Why electric vehicles matter

Carbon emissions and pollution are an ever-growing threat to nature and society, and electric vehicles minimize those because of its distinct traits versus a conventional car or vehicle.

Electric vehicles have no tailpipe, hence produce zero carbon dioxide emissions, which results in reduced air pollution in the long run. They’re also generally quieter too, which helps reduce noise pollution. Another thing is that it you only need to recharge its batteries at a certain period instead of refueling at a gas station, which saves you cash in the long run.

Only drawback of electric vehicles vs conventional cars in terms of emissions is that constructing the former utilizes more energy than the latter, although it’s worth noting that with the fast advancements of our technology today, manufacturers are bound to find a solution for this.

Electric vehicles are the future

Manufacturers like Tesla popularized the innovation, and more and more mainstream manufacturers that have strong presence in the Philippines are adopting this technology. To date, use of electric vehicles aren’t that popular yet locally because of lack of public charging points and these products aren’t marketed in general, but the likes of Nissan, Mitsubishi, and Hyundai already have some electric vehicles in our shores. With the strong value electric vehicles provide, it’s not hard to imagine a future where they electric vehicles populate Philippine roads.

Electrical Safety Tips for the Industrial Workplace

The safety of a workforce is very important in all workplaces, particularly the safety of workers exposed to electrical hazards that can potentially cause harm. Within the trade industry, builders, machinists, and other workers are surrounded by potential electrical hazards in their day-to-day role. From electrical wiring, machinery, and exposed cables, it is vital for the employees to know how they can remain safe at work. Here are some important tips to ensure safety in any trade working environment:

Protect your facility’s system

There are various components in the market that can provide the necessary protection for your facility’s system. An example is the Mersen’s complete set of solutions such as the Surge-Trap Surge Protection Devices, Smart Automatic Recloser, and Ground Monitoring. Here’s a video showing how these components can protect you and your facility:

Complete a risk assessment

Before any worker enters the premises, he/she should complete a risk assessment on site. Its purpose is to be able to identify the risks or injuries that could be caused. It should take into consideration the type of electrical equipment used, how it is used, and the environment that it is used in. There are five stages that must be completed in a risk assessment to ensure safety:

  • Identify any electrical hazards and the electrical system or process
  • Identify the electrical work to be performed within the electrical system
  • Evaluate the risks and decide on precautions to take
  • Record your findings and implement them
  • Review the risk assessment and update when necessary

Complete the lockout/tagout procedure

To ensure the safety of fellow workers when a machine is turned off, the lockout/tagout is a key procedure. It is especially useful when maintenace or repairs are being carried since it ensures the re-energisation of a machine doesn’t occur. All workers who use machinery should be thoroughly trained on the lockout/tagout program before beginning work, as well as being provided with the correct lockout tagout equipment.

Don’t overload outlets

The use of electrical adapters is useful to power more electrical machines but it isn’t always safe, particularly in a busy and crowded working environment that tradespeople often work in. If using extension leads, it should be ensured that appliances or tools plugged into the outlets does not exceed the maximum current rating stated for the extension lead. Overheating and/or fires may occur if power outlets are overloaded.

Ensure you use safety signage

Safety signages are a must to help warn people of hazards, as well as to indicate or prohibit certain actions. Warning and dangers signs should always be positioned within proximity of the machine or equipment – for the benefit of both the workers and visitors or contractors who will visit the site. There are four types of safety signs that should be included within your workplace’s health and safety program: mandatory (blue), prohibition and fire (red), caution and safe condition.

Maintain your equipment

Machines and equipments should always be checked for wear and tear, with regular services and cleaning. The goal is to keep machinery, tools, and equipment healthy and safe for as long as possible to avoid the need for repairs. By checking for signs of wear and tear, you are less likely to suffer any electrical issues and injury to workers without spotting the warning signs first.

Will Electric Vehicles Take Over?

As time passes by, and our daily lives become more hectic, cars, planes, trains, and ships are having a growing impact on the climate. A quarter of the world’s greenhouse gas emissions is generated by transportation. In 2016, transportation (including ships, aircraft, and railroads) in the United States alone produced more carbon dioxide emissions than any other sector. Shifting from gas-powered vehicles to those that run on electricity will play a key role in curtailing climate change – in order for countries to minimize carbon emissions. 100 million electric vehicles (EV) must be on the road by 2030.

Fighting Climate Change and Saving Money

Electric vehicles run on battery power. Whenever it reaches a low battery status, it has to be charged at home or a charging station.

While EVs are in motion, they are clean since it doesn’t emit carbon dioxide or any other pollutant. But then, how clean these EVs are depend on how the electricity powering them is generated. For example, a report by the Union of Concerned Scientists says that EVs that generate power from renewable power sources like wind or solar which produces virtually no global warming emission. Even then, EVs powered by electricity generated mainly from coal produced fewer global warming emissions than a fossil-fueled vehicle averaging 27 miles per gallon.

Although upfront costs of EVs are higher than fossil-fueled vehicles, EVs can be cheaper to maintain since it doesn’t require oil changes or regular maintenance. In addition, electric vehicles can save $750 to  $1,200 a year on fueling compared to a fossil fuel vehicle averaging 27 miles per gallon.

The World is Going EV

In the United States alone, electric vehicle sales are increasing, reaching almost 200,000 in 2017 – a 25% increase over 2016.

Many countries such as Germany, India, Ireland, Israel, and the Netherlands have announced plans to ban fossil fuel cars starting 2030; Britian, France, Taiwan, and California will ban them in 2040; and Norway in 2025. Meanwhile, Paris, Rome, Madrid, Athens, and Mexico City will ban them diesel vehicles in 2025.

China, the world’s biggest car market, will no longer approve any new fossil fuel car projects. A policy effective in 2019, requires automakers that manufacture or import over 30,000 vehicles per year to earn fuel-consumption credits and achieve quotas for producing zero and low-emission vehicles. China will also soon ban fossil fuel vehicles and will soon phase them out on the island of Hainan in a test run. Beijing, the capital of China, wants at least 20% of their vehicle production to be electric and hybrid by 2025.

The Future of EVs

As we know by now, EVs are cheaper to run and maintain than fossil fuel cars since they have fewer moving parts. The next big challenges to tackle are range anxiety and charging time. Most EVs can run between 50 to 200 miles on one battery charge. When electric vehicles reach 700 miles per charge – which may not take long, considering EV ranges have already doubled within the past three to four years – it will be a game-changer.

Battery makers are working to improve to enhance battery energy density to make it lighter and the chemistry of lithium batteries so they don’t require as much toxic material. These developments will significantly lessen the environmental impacts of electric vehicles and improve their efficiency.

A number of charging innovations are in the works too. Such as wireless charging pads in parking lots, wireless charging under roadways and solar roofs.

Also, the more renewable energy sources there are, the cleaner electric vehicles will get. In addition, as batteries improve, wind and solar power will become more reliable.

The electric vehicle revolution is coming. It’s not question if “if”, it’s a question of “when”.
