Battery Powered Dielectric Fault Analyzer is mainly used for monitoring acoustic emissions which refers to a nonintrusive in-service test for monitoring acoustic signals produced by partial discharge and loose components. The Dielectric Fault Analyzer DFA100 is specifically designed to detect faults in grounded gas-insulated systems, such as filled dead tank circuit breakers. The Dielectric Fault Analyzer can also be applied to grounded oil filled instrument transformers. Battery Powered Dielectric Fault Analyzer can be directly applied to any grounded component that is associated with the filled apparatus under test.
