What Are the Types of High Voltage Circuit Breakers in a Substation?

There are a few different types of circuit breakers that are used at variable voltages – either medium or high – and they can be implemented into a number of electrical systems.

Electrical Substation: Equipment, Types, Components & Functions

High Voltage and Medium-voltage switchgear such as oil circuit breaker, SF6 circuit breaker, air circuit breaker, gas circuit breaker, and vacuum circuit breakers are used to switch electric circuits and substation

The basics of high voltage switching equipment in power

Air blast breakers, used for EHVs (≥345 kV), are no longer manufactured and have been replaced by breakers using SF6 technology. Oil circuit breakers have been widely used in the utility industry in the

Selection of a circuit-breaker

If the transformer is located in a consumer''s substation, certain national standards require a LV circuit breaker in which the open contacts are clearly visible such as withdrawable circuit breaker.
