9.3.4.8 Instantaneous residual overcurrent protection EFPIOC
Main menu/Settings/Setting Group N/Current protection/
InstResidualOverCurrent(PIOC,50N)/EFPIOC:x
Displays some instances of EFPIOC with settable parameters per instance. The
settable parameters are operation (On or Off), base setting for current magnitude,
the threshold current as a percentage of IBase, and the multiplier for the current
threshold level.
