Transient Earth (Ground) Fault Protection

Transient Earth Fault Protection (TEF) (also referred as Transient Ground Fault) allows the controller to be configured to detect transients earth faults in compensated or isolated neutral networks. Depending on the configuration, the controller will alarm or trip when a TEF is detected.

TEF detection and direction determination are derived by processing and evaluating the neutral-point displacement voltage and the residual current waveforms using a TEF process method.

NOTE: This feature is comprehensively documented in Application TEF in AppNote_TEF_A50-15.xx.
