What is An Electrical Transformer?

An electrical transformer is a machine that transfers electrical energy from one circuit to another via electromagnetic induction without changing the frequency.  It is a vital device in power transmission that links the generating stations and the users. A transformer comprises a pair of coils, wound around a laminated magnetic core. The winding that supplies … Read more

What is a Molded Case Circuit Breaker?

A molded case circuit breaker (MCCB) is a type of breaker that protects electrical circuits from overcurrents arising from overload, short circuits, or faulty wiring. It is like a miniature circuit breaker (MCB), however, MCCB has higher features. Molded case circuit breakers have a higher current rating of up to 2500 amp and an adjustable … Read more

What is a Miniature Circuit Breaker (MCB)?

A miniature circuit breaker is a safety switch that protects an electrical circuit from overcurrent or power surge. It is a protective device that interrupts the circuit when there are high currents.The primary function of a miniature circuit breaker is to protect an installation or branch circuit against high current arising from overload or short circuit. … Read more

What is an Oil Circuit Breaker?

An oil circuit breaker is a type of breaker that uses oil as an insulation medium for arc extinction. It is an essential device in the power system that uses insulating oil as an arc quenching medium. Oil circuit breakers use fixed and moving contacts for in circuit protection in both substations and transformers Each … Read more

What is an SF6 Circuit Breaker?

An SF6 circuit breaker is a device that uses sulphur hexafluoride gas as an arc quenching medium. It is the type of circuit breaker used to protect power systems, electrical grids, and distribution stations. SF6 gas has strong electronegativity and arc quenching properties, making them a better insulating medium than air and oil circuit breakers. … Read more

How to Tell If a Circuit Breaker is Bad

Maybe your circuit breaker trips always and you want to know if the device has gone bad! A breaker can go bad, but rarely. A tripping breaker can be a warning sign of overload, short circuits, wrong wiring, ground faults, and a bad breaker. You need to find out what is tripping the receptacle before … Read more

What are the Different Types of Circuit Breakers?

Though we have different types of circuit breakers, they all protect electrical devices. Circuit breakers protect electrical equipment from short circuits, over-currents, fire outbreaks, electric shocks and ground faults. It is a must-have receptacle for every homeowner as required by the National Electrical Code. Circuit breakers come in varying sizes and models, ranging from the … Read more
