Instantaneous phase overcurrent protection PHPIOC (50)

Main menu/Settings/Setting Group N/Current protection/
InstPhaseOvercurrent(PIOC,50)/IOC
Displays some instances of PHPIOC (50) with some settable parameters per instance.
Operation mode, operate current multiplier, operation on or off, operate phase current
level as a percentage of IBase, and IBase itself are the settable parameters available here.

Instantaneous residual overcurrent protection EFPIOC (50N)

Main menu/Settings/Setting Group N/Current protection/
InstResidualOverCurrent(PIOC,50N)/IEF
Displays some instances of EFPIOC (50N) 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.

Main menu/Settings/Setting Group N/Current protection/
PhaseOverCurrent4Step(PTOC,51_67)/TOC
Displays some instances of OC4PTOC (51_67) each with several settings. The settings
range from base current and voltage settings to parameters for customer programmable
curves.
