Switchgear refers to the combination of electrical disconnects, fuses and/or circuit breakers used to isolate and de-energise electrical equipment to allow work to be done and to clear faults downstream. Switchgear & Controlgear are indispensable not only in transmission and distribution of power, but wherever there is a need to access and control electricity. 
The Indian Switchgear Industry manufactures the entire range of circuit breakers from bulk oil, minimum oil, air blast, vacuum to sulphur hexafluoride as per standard specification in the entire voltage range from 240 V to 800 KV. This Sector in India has a fully developed mature industry, producing and supplying a wide variety of Switchgear and Controlgear items needed by the industrial and power sector. 
Secondary equipment such as relays/Controlgear used for various types of fault protection have made significant advances due to major developments in the field of electronics. Owing to technology advancement, compact size & reliability, digital relays have become popular. As per recent trend, in addition to protection and control of power, monitoring and signalling are becoming integral parts of Switchgears.
