Low Voltage Switchgear Standards and Testing

Generally all Switches, Switch Disconnectors, Disconnectors and Fuse combination units are designed to comply with the requirements, Standards and Testing. All are comply with the requirements of IEC 947-3 or EN 60947-3. This is also requires a combination of type tests and routine tests before installation. For this reason normally a sequence of type tests is required to prove that it compliance with the standard. In this post we will learn about the Low Voltage Switchgear Standards and Testing with Read More …

Circuit Breaker Operation Principle

It’s true that switchgear use to perform the most arduous duty when it is in operation. For better understanding we will learn the about the circuit breakers operation in switchgear operating principles. It will be easy to understand switchgear operation principle if we know circuit breaker operation principle. So let’s go. Circuit Breaker Operation Principle: Construction: Once I dismounted a 1000A MCCB. I found out the heart of a traditional circuit breaker is the contact system. Circuit breaker usually consist Read More …

Introduction of Switchgear

Switchgear is responsible to connect and disconnect the electric power supplies and systems. Switchgear is a general term which uses to covers the switching device and its various combinations with some associated control, measuring all parameter, protective and regulating equipment, together with accessories, enclosures and supporting structures. Switchgear mainly applied in electrical circuits and systems from low voltage like domestic 220/240V applications to transmission networks up to 1100 kV. To set up this control system a wide range of technology Read More …
