In a Solidly grounded system, the neutral is directly connected to the earth without any intentional resistance or reactance in between. Compared to the other grounding systems, the transient overvoltages…
An electrical system that is not intentionally connected to the ground is known as an ungrounded system. Even though the system is not connected to the ground, there exists a…
Image source: electronics.stackexchange.com Ideally, the voltage measured across the neutral and the earth/ground must be zero. But sometimes there exists some measure of potential difference between them. Here, in this…
This article discusses several types of grounding methods. The intention of providing the proper ground is to control the voltage with respect to the ground and provide a low resistance…
What are current collectors? Current collectors are components fitted to an electric equipment in motion to collect electric current required for its operation from a stationary busbar. They can be…
What is an instrument transformer? Instrument transformers are current and voltage transformation devices that are used to step down the transmission and distribution line voltages and currents to levels that…
Anyone who uses electricity and have heard of terms: single-phase and three Phase, maybe trying to understand the difference between them. This article narrates the differences between a single-phase power…
You might have noticed huge towers supporting the high voltage transmission lines in your locality. These high voltage lines transmit electric power generated at power stations which are situated at…
Short Circuit A short circuit occurs when two or more current-carrying conductors of different phases or different voltage levels or different terminal (in DC circuits) come in contact with each…
In an AC power system, the power factor is a very important parameter that defines how efficiently electrical power is being utilized by the load. It is a rational number…
