SF6-filled monitoring for Power Supply

SF6-filled monitoring for Power Supply

The acoustic emission diagnostic technique is a nonintrusive in-service test used for monitoring acoustic signals produced by partial discharge and loose components. The DFA100 is specifically designed to detect faults in grounded SF6 gas-insulated systems, such as SF6 filled dead tank circuit breakers.
