A common phenomenon observed during the operation of high voltage transmission devices is the occurrence of small arcs, mainly while operating devices like isolators. Here we briefly discuss why it occurs even when the circuit breaker is open.
The Phenomenon of Arcing...

Electrical isolation is a safety protocol that involves cutting off the electrical supply to a piece of equipment or an entire system. This is done to ensure that the equipment or system is not accidentally energized, which could lead to electrical shock...

An isolator is a crucial component in the electrical power system. It is a type of switchgear that provides a means to disconnect a part of the electrical circuit when it is under no-load condition. It is a manually operated device, designed to disconnect...

Earth Leakage Circuit Breakers (ELCB) and Residual Current Circuit Breakers (RCCB), while both share the purpose of safeguarding individuals, their approaches and functionalities differ significantly.
ELCB (Earth Leakage Circuit Breaker)
An ELCB, also known as an earth fault circuit breaker, is a protective device designed to detect and interrupt leakage current flowing to earth. ELCB relies on voltage sensing. If any leakage occurs from devices or live line to the earth wire, it flows...
