Miniature circuit breakers commonly known as MCB, are mechanically operated switches cum circuit protection devices. It is an electro-mechanically operated automatic circuit protection device and is used to interrupt a…
Introduction Circuit breakers are safety devices, which ensures the safety of equipment and personnel from electric shocks and damages. They are self-acting and should safely interrupt the current flow on…
The circuit breakers and isolators serve a common purpose of circuit interruption. The primary difference between them lies in their behavior during faults in the circuit. In this article, let's…
Transformer action is a phenomenon by which EMF(Electro-motive force) is induced in from one coil to the other coil by electro magnetic induction. It is the basic principle of electric…
MCB (Miniature circuit breaker) is a re-settable device designed to protect a circuit from short circuits and overcurrents. The trip curve of an MCB (B, C, D, K, and Z…
MCB – Miniature Circuit Breaker and RCBO – Residual Current Circuit Breaker with Overload Protection are circuit protection devices. These devices are commonly used in low-voltage power distribution and can…
A Buchholz relay in a transformer is an oil-activated relay, used to sense abnormalities such as short circuits, overheating, and oil leakages inside a transformer. It is a cylindrical object…
Before getting into the topic, we have to keep two points in mind.1. Conventional Current flow. (The way Current is said to flow historically)2. Actual current flow. (The way Current…
Kilowatt is the unit of power. It is the product of voltage, ampere, and power factor. It is also called real power. One kilowatt(kW) is equal to a thousand watts(W).…
