What is switchgear? Any mechanical switching devices used to make or break the current flow and their combination with measuring and control devices are known as switchgear. This includes circuit…
An earth leakage can represent a danger to life or property if it is not located and mitigated. Studies have revealed that at least 500 people experience electrocution every year…
It is necessary to select the correct rating of switchgear for any application. Therefore, during selection, it is necessary to know the characteristics of the load. The International electrotechnical commission…
Earth fault is an undesirable condition at which current flow from a conductor to earth. This can happen when a current-carrying conductor falls on the ground or the body of…
When a circuit breaker interrupts high currents, an electric arc is generated. An electric arc is the discharge of electric current through gas or air. The conduction of electric charges…
A relay is an electrically controlled switching device. It consists of an electromagnet and a set of contacts that open or close when voltage is applied to the electromagnet. It…
Every motor must be protected from all possible faults to ensure prolonged and safe operation as well as time loss caused due to breakdown. Almost all the industries rely on…
MCB stands for miniature circuit breaker. It is a circuit protection device, capable of protecting a circuit or a piece of equipment from greater damages caused due to short circuits…
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…
Miniature circuit breakers commonly known as MCB, are mechanically operated switches cum circuit protection devices. It is an electro-mechanically operated automatic circuit protection devices. An MCB is used to interrupt…
