Mechanical Wear Characteristics of 170 kV Gas-Insulated Switchgear Circuit-Breaker Contacts Before Arc Initiation: An Accelerated Lifetime Test Approach

Mechanical Wear Characteristics of 170 kV Gas-Insulated Switchgear Circuit-Breaker Contacts Before Arc Initiation: An Accelerated Lifetime Test Approach

This study investigates the mechanical wear characteristics of 170 kV gas-insulated switchgear (GIS) circuit breaker contacts by conducting accelerated life testing. Samples identical to those used in 170 kV GIS were subjected to up to 20,000 cycles, which is the maximum guaranteed lifespan. Visual...
