Current transformers (CT) and Potential Transformers (PT) are instrument transformer types used to step down transmission or distribution line voltages and current to the level that can be measured using…
RCCB stands for Residual current circuit breakers and MCB stands for Miniature circuit breakers. Both of them are basic circuit protection devices found in the distribution boards of every house…
In the world of industrial automation, Programmable logic controllers (PLC) and Distributed Control Systems (DCS) are used to control or automate a process or a machine. They monitor the field…
Electromagnetic induction occurs whenever there is a relative motion between a magnetic field and a coil. The electromagnetic force acts on the charged particles inside the coil, forcing them in…
The terms, motor rated current, full load current and nominal current, are very likely to confuse electrical engineers. Even though these terms are quite similar, there are slightly different from…
An electric motor is an energy transformation machinery. It transforms electrical energy into mechanical energy. In other consumes electrical energy and delivers mechanical energy in the form of rotations. For…
The bipolar junction transistors exist as NPN and PNP types. This article intents to help you understand the difference between these two types and how to use them in a…
Circuit breakers are employed to automatically switch off a circuit or a load whenever any abnormalities in current flow are detected. This functionality of the circuit breakers is known as…
A certain amount of current is drawn by a transformer from the source connected to it primary even when no load is connected to its secondary. A part of this…
kW and kVA are units of power. kW stands for kilo-watts and kVA stands for kilo-volts ampere. Let's see what is the difference between kW and kVA and how to…
