Both an earth leakage relay and an earth fault relay are electrical protection devices used to safeguard humans and electrical equipment from earth leakage or faults. The fundamental difference between an earth fault relay and an earth leakage relay is that an earth fault relay is designed to detect a high earth fault current that…
A manual transfer switch is installed adjacent to the main service panel to replace the conventional electrical supply with power from a backup generator during a power outage. Automatic switches detect the loss of power, start the backup generator, and switch over to the backup power feed. In contrast, manual transfer switches require an operator…
Ever heard of the term “contactor” in the field of electricity and electronics? From the name alone, you can imagine it is a device that works by coming into physical contact with another. Generally, contactor is a switch that can be turned on or off by an electric current. They are commonly used in power…
It’s been a few years since you purchased your home and you’re getting ready to move. You’ve decided to rewire the house, but are wondering how disruptive the process is. The answer? It depends. What does that mean? Well, we simply mean that rewiring a house can be a messy affair, or it can be…
Because measuring the high voltages and currents involved with power transmission and distribution networks is difficult, instrument transformers are frequently employed to scale these values down to a more manageable level. This is because measuring meters or instruments and protective relays are low-voltage devices that cannot be directly linked to a high-voltage circuit for system…
The cost of rewiring a house ranges from $3,000 to $25,000. The cost of home rewiring includes both labor and materials costs, which may vary depending on the age and size of your home. In other words, rewiring a home entails removing the old wires and replacing them with a contemporary, non-metallic wire enclosed in…
Do you have a transformer? If yes, chances are you only care about the output that you will get from it. Have you ever bothered to know the mechanisms behind its operations? Like knowing the parts and components that make up a transformer? A transformer is an electrical device that transfers energy from one circuit…
In recent months, consumers and manufacturers have been paying close attention to low-voltage domestic power conservation gadgets. It’s commonly utilized in residential dwellings to save energy and lower utility expenses. It’s a little device that you may connect to any of your house’s AC outlets (Mostly near the Energy Meter). Furthermore, some companies claim that…
When it comes to wiring electrical devices, there are three popular types: live wires, neutral wires, and earth wires. There are a lot of misconceptions about these three types of electrical lines. Chances are you might have been lured or deluded by some of these misconceptions. Don’t worry, we are here to demystify some of…
Do you know the difference between conductor and insulator? It’s not just a question of what you can wear in cold weather. Electrical circuits need to be insulated, or they will short out and stop working. If a wire is running inside an electrical device, like a lamp, it must be insulated so that any…
