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.
