Pole-mounted Vacuum Circuit Breaker Testing Room

Isolation testing room and workstation for PVB

Pole-mounted Vacuum Circuit Breaker Assembly line

The equipment configuration consists of partial discharge testing isolation room, automatic connection station with insulation configuration, electrical isolation device, detection equipment, etc.

Partial discharge test (PD test) for pole-mounted vacuum circuit breaker (PVB) is an important means of evaluating the insulation performance of switch equipment, used to detect whether there is any PD phenomenon inside the switch. Partial discharge is a small discharge phenomenon caused by the local electric field strength inside or on the surface of insulation materials exceeding the dielectric strength of air or solid insulation materials. Long term existence of partial discharge can accelerate the aging of insulation materials and ultimately lead to insulation breakdown.
