Transformer: Power versus Distribution

A transformer is a type of electrical component that transfers energy from one circuit to another. It is made out of coils, producing a varying magnetic flux, and through Faraday’s law, produces an electromotive force. Overall, a transformer performs different tasks. First, the transfer of electrical energy from one circuit to another by electromagnetic induction. Next, the capacity to transfer electrical power without changing frequency.

Transformers, like every other component, have varying types; Power Transformers and Distribution Transformers. Both transformers have different in their purpose.

Power Transformer 

These are employed in power plants and transmission substations. Which serves the purpose of stepping up the voltage to ensure consistency of voltage through long range transmission. It increases or “steps-up” the voltage of generated electricity. It can travel through long transmission lines with consistent voltage and power. 

Distribution Transformer 

It is applied in distribution stations, industrial and home settings. It “steps-down” the voltage that the power transformer recently increased. Additionally, it is utilized in residences and other settings that use 230 volts or less.

Both transformers perform a crucial part in energy transmission, distribution, and usage in our daily life. With one as an amplifier to ensure constant transmission of electricity. While the distribution, as safety converter of electrical power to household levels. 

At PowerPro, we offer various types of power and distribution transformers. They are designed to ensure the reliability, durability, and efficiency required in utility, industrial, and commercial applications.

Circuit Breakers vs Switches: Can It be Interchanged?

Circuit breaker and Switch

Circuit breakers and switches are crucial for the safety in homes and industry. For industrial purposes, these devices need to be able to handle a higher capacity compared to a residential setting. But can circuit breaker be used as switch? Before going into that, let us first identify the difference between the two.

Circuit Breaker

A circuit breaker is a safety device used to prevent damage to motors and wiring. It does its job when the current flowing through the electrical circuit exceeds its design limit. It happens by removing the current from a circuit when unsafe circumstances arise. A circuit breaker automatically does this and shuts off the power immediately. In this way it works as an automatic service protection device. This is what makes the circuit breaker different from a switch.

Switch

A switch controls the flow of the electrical current within a circuit. It is used to inhibit or initiate the flow of the current. It manually cuts and reconnects the power from an electrical supply by creating or closing an air insulation gap between two conduction points. A switch is designed to power on and off.

The Difference

Circuit breakers break and switches switch. These differences are very important to consider in understanding their safety and practicality. Circuit breaker is not to be used as a switch due to issues of endurance. Switches are designed for use in multiple times of operations. It is meant to endure many times of turning on and off. Circuit breakers are not meant for nearly the same amount of operations as switches. Cycling a circuit breaker on and off multiple times will result in its eventual failure. However, some circuit breakers are rated for switching duty for lighting circuits, such as those applied in 120V 277V fluorescent lighting circuits (marked SWD or HID). SWD means Switching Duty while HID signifies High Intensity Discharge lighting. The UL489 Standard for MCBs states that SWD circuit breakers can be rated up to 20A, no more. HID breakers are rated up to 50A.

It is quite obvious by now that though they share a similar function on a basic level, they still are two different entities. It may work more effectively as safe switches, but they are not switches. They are not interchangeable. That being the case, circuit breaker as a switch is not recommended. 

Meanwhile, another question can be raised from this. Can switches be used in place of circuit breakers? Since switches are not designed to detect and interrupt an overload or faulty conditions, it would likely melt or burst into flames. Using a switch in replacement of the circuit breaker causes more problems. Switches switch and circuit breakers break. Don’t get confused with that.

Solar PV System Needs Surge Protection

Surge protection devices help keep systems running smoothly and profitably. Solar arrays are just like electronic devices that we use. These are prone to surges in voltage that can harm its components, reducing its purpose to convert energy.

Power surge significantly happens when more voltage comes through wires into devices. Some reasons include electrical overload, faulty wirings, lightning strikes and restoration of electricity after an outage. A harmful incident can occur, and in the worst case scenario, may lead to burning of the establishment. 

Solar arrays are electronic devices that are also prone to damage from surges. Solar panels are prone to lightning due to its large surface area and placement in exposed locations. These are mostly mounted in open spaces.

If the solar panels are struck directly, severe damage happens. Lightning burns holes in the equipment and even causes explosions. Loss of a PV module will only mean a loss of a string. But loss of inverter is a loss of the power generation for a large section of the plant. The effects of lightning and other overvoltage are not always apparent. These events not only affect and destroy major modules and inverters, but also monitoring systems and tracker controls.

A surge protector prevents damage to electronics by diverting the overvoltage from the power line into a grounding wire. Random and unexpected failure of solar arrays due to surges could slow down financial return. Installing surge protection device networks throughout the solar array’s DC and AC distribution protects the system from critical surges.

SPDs have its certain limitations too. For example, SPD can not prevent damages from direct lightning strikes. Adding lightning protection device can be taken to further protect the system specifically from lightning.

Electricity Safety Tips to Know at Home

Electricity is a basic need at home. It can be dangerous if not treated and used properly. Electricity safety is one of the most important measures you should keep in mind.

Here are some electricity safety tips you should do at home:

1. Always Turn off the Power

Turn off and unplug appliances when not in use. If you ever have to deal with electrical issues, always cut the power at the breaker box. Before repairing, always confirm that the outlet, fixture or switch is always off. 

2. Fire Extinguisher Availability

The availability of fire extinguisher helps in prevention of fire hazards. It is better to use a fire extinguisher in case of a fire. Water is a well-known conductor of electricity. Using water to put out a fire may cause electrocution and shock hazard for someone putting the flames out. Ensure a fire extinguisher is rated to handle electrical fires.

3. Use More than One Outlet

It is not a safe setup to have one outlet strip with a number of appliances plugged to it.  It is best to distribute small appliances and electronic devices to multiple outlets. This will avoid overwhelming the only used outlet.

4. Watch Out for Warm Outlets

Outlets should always be cool to touch. Having a warm outlet can mean an electrical fault inside it. If this happens, shut the circuit off of the breaker box and call an electrician immediately.

5. Child-proof Your Outlets

Children are playful and always curious. Installing outlet covers can protect them from electrical shock. It is even the best choosing spring-loaded covers that automatically close when nothing is plugged in. 

6. Invest in Circuit Interrupters

Circuit interrupters prevent types of fire that can kill and injure lots of people. It is also helpful to avoid damaging your property when electrical wiring has too much current flowing. 

7. Examine Flickering Lights

Flickering lights may indicate loose wires on the circuit. It may also be a bulb coming loose. Tighten the bulb to gain sufficient electricity flow. If it doesn’t fix it, call an electrician.

8. Extension Cords are for Short Term

Extension cords are meant for short-term use. These are not listed, labeled and rated for permanent use. With continuous use over a long period of time, extension cords can deteriorate. It can create a potentially dangerous electric shock and fire hazard. Install additional outlets where you need them.

Electricity is a cornerstone of modern living. As the saying goes, “Prevention is better than cure.” It is important to take note of these simple electricity safety measures to steer clear of its threats. Make sure to call a licensed electrician when it comes to electricity. It can save you a lot of time and money. Mostly, it will save your property and family at risk.
