Operator's manual
Displays some instances of PHPIOC 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

Main menu/Settings/Setting Group N/Current protection/
InstResidualOverCurrent(PIOC,50N)/IEF
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.

Four step phase overcurrent protection OC4PTOC

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

Pole discordance protection CCRPLD

Main menu/Settings/Setting Group N/Current protection/
PoleDiscordance(RPLD,52PD)/PD
Displays instances of CCRPLD with some settings per instance. The settings are
for operation, base current, trip time delay, contact function selection, current
function selection, asymmetrical magnitude of current and current release threshold.

Four step residual overcurrent protection EF4PTOC

Main menu/Settings/Setting Group N/Current protection/
ResidualOverCurrent4Step(PTOC,51N_67N)/TEF
Displays some instances of EF4PTOC with a large number of settings per instance.
Typical settings are those for harmonic restraint, minimum fundamental frequency
current level, base settings for current and voltage and several others.
Sensitive directional residual over current and power protection
SDEPSDE
Main menu/Settings/Setting group N/Current protection/
SensDirResOvCurr(PSDE,67N)/SDE
Includes voltage, current, operation mode and timer settings.
