Figure 164: Connection to IED with two analogue voltage inputs
Some settings are required for the analog voltage inputs in the IED. The voltage ratio
for the inputs shall be set 1/1, for example, VTSecx = 100 V VTPrimx = 0.1 kV
The analogue inputs are linked to a pre-processor (SMAI) block in the Signal Matrix
Tool. This pre-processor block must have the same cycle time, 8 ms, as the function
block for STTIPHIZ (64S).
The default parameter settings shall be used for the pre-processor block.

Operation to be set Enabled to activate the stator earth-fault protection
RTrip is the resistance level,set directly in primary Ohms, for activation of the trip-
function.
RAlarm is the resistance level, set directly in primary Ohms, for activation of the
alarm-function.
tAlarm is the time delay to activate the ALARM signal output when the measured fault
resistance is below the set RAlarm level
VLimRMS is a setting that controls the output VRMSSTAT: if the total RMS voltage
measured by the function at the injection point is above the setting VLimRMS then the
