Common problems in medium voltage switchgear
Electrical switchgear: how it’s got its name? Many years ago power stations used simple disconnectors, open knife switches, to isolate or de-energize equipment. With the continuous increase in power levels, it became no longer safe to open such disconnectors manually and geared switches were a need which is then combined to be “Switchgear”. Switches didn’t […]
Vacuum Circuit Breaker (VCB) – An Introduction to its Principle, Construction, and Operation
A Vacuum Circuit Breaker, or VCB for short, is a specialized type of circuit breaker that utilizes a vacuum as the arc quenching medium. This unique design allows it to offer superior arc quenching properties compared to other types of circuit breakers, such as those using oil or SF6 gas. The principle behind the functioning […]
Functional & Operational Tests For Medium Voltage Circuit Breaker Operating Mechanism Components
Medium voltage circuit breakers play a very important role in medium voltage switchgear( metal clad, metal enclosure,…), and operating mechanism electrical and mechanical components functional tests is one of the most important tests for circuit breakers in panels. In this article, we have tried to talk about these tests briefly and in a list. Functional & […]
