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.
9.3.4.6
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.
9.3.4.7
Four step directional negative phase sequence overcurrent
protection NS4PTOC
Main menu/Settings/Setting group N/Current protection/
NegSecOverCurr4Step(PTOC,46I2)/NS4PTOC:x
Displays instances of NS4PTOC.
9.3.4.8
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.
9.3.4.9
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.
9.3.4.10
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.
