SE_P14x_EF
MiCOM P14x shaped directional / sensitive earth-fault element (ANSI 50N/51N/67N/SEF) with a residual-voltage polarised forward sector.
When to use it
Use SE_P14x_EF when a feeder needs residual-current earth-fault detection modelled in the PLC, and — on a network with more than one earthed source — the decision has to be made directional so the healthy feeder does not answer for the faulted one.

Supervised control write
SE_P14x_EF commands a real actuator. It is written to sit underneath your own interlock, permissive and protection logic — not to replace it. Commission it as you would any control block you wrote yourself.
