high voltage CIRCUIT BREAKER gas Purpose Detect

high voltage CIRCUIT BREAKER gas Purpose Detect2012/11/16The earliest circuit switchers were designed and supplied as a combination of a circuit breaking interrupter and an in series isolating disconnect switch. These earliest models (see Fig. 1) had multiple interrupter gaps per phase on above 69 kV interrupters and grading resistors, thus the necessity for the in series disconnect switch.
