Switchgear is a centralized collection of circuit breakers, fuses and switches that function to protect, control and isolate electrical equipment. Metal structures are used for mounting circuit protection devices. A collection of one or more of these structures is called a switchgear line-up or assembly.
Electric utility transmission and distribution systems as well as in medium to extensive sized commercial or industrial facilities are where switchgears are usually found. Switchgear servicing & maintenance is critical for plant’s success.
Essential Features of Switchgear
- Complete reliability: The requirement for switchgear is more and more critical because of the interconnection and increasing capacity of generating stations.
- Able to distinguish a fault: When a flaw is found on any point of the power system, the switchgear must be able to figure out the faulty section and the healthy section.
- Quick operation: If there is something wrong on any part of the power system, the switchgear must operate quickly so that no damage is done to generators, transformers and other equipment by the short-circuit current
Thus we see how vital Switchgear servicing & maintenance is for the proper working of the framework. There are great websites where you can understand switchgear and how to service it frequently.
