gascircuit breakers Components Detection for 220kv

Air circuit breakers (ACB): ACBs can be used both as circuit breakers of low voltage electrical distribution systems and for protection of electrical equipment in facilities and industries.A common breaking principle is to use the magnetic field, created by the current through the ACB, to force the arc towards insulating lamella.
