The HV circuit breakers extinguish such arcing and permit the safe and reliable operation of the feeders. Below listed are few types of high voltage circuit breakers, some are both used as medium voltage or high voltage circuit breakers. Vacuum circuit breakers are used for a voltage range of 3 kV to 38 kV.
High voltage direct current circuit breaker is used for breaking the direct current circuit during the fault. It is quite interesting since we need to break the circuit at the circuit current is non zero. As you know, AC circuit breaker breaks the circuit and quenching the arc naturally. Since AC has a natural zero points.
Because the high voltage circuit breaker (CB) is the most essential element of HV switchgear, it must have particular properties for safe and dependable operation. Defective high-voltage circuit breaking and switching are extremely infrequent.
High voltage vacuum circuit breakers have been in use as an alternative to high voltage gas circuit breakers since 2014. They have been extensively used in distribution systems for the making and breaking of fault current and the switching of loads for 30 years. Vacuum circuit breakers are a type of high voltage switching equipment.
