3BHE042816R0101 PCD244A101 ABB Excitation control of medium and high voltage frequency conversion board

Description

RFs-Adjust
Simulated ground fault resistance used as a reference value
for calculating REs in the ‘REs-Adjust’ mode.
MTransRatio
V.t. ratio when primary system directly grounded.
NrOfStarpt
Number of star-points in the zone of protection.
VoltageInpUi
defines the voltage I/P channel for the reference voltage.
VoltageInpUs
defines the voltage I/P channel for the measured voltage.
2.StarptInp
Binary address used as status I/P. It determines whether the
second star-point is connected in parallel to the first.
(FFALSE, TTRUE, binary input or output of a protection
function).
AdjMTRInp
switches the protection function to the MTR determination
mode.
(FFALSE, TTRUE, binary input or output of a protection
function).
AdjREsInp
switches the protection function to the REs determination
mode.
(FFALSE, TTRUE, binary input or output of a protection
function).
BlockInp
Binary address used as blocking input.
(FFALSE, TTRUE, binary input or output of a protection
function).
Trip
Output for signalling tripping
(signal address).
StartTrip
Output for signalling the pick-up of the tripping stage
(signal address).
