Activating/deactivating function monitoring
If the measured value leaves the current bandwidth (desired value +/- band-
width) for more than 15 minutes without a tap-change operation taking place,
the function monitoring relay is activated. This results in a message on the
display which is only reset when the measured value returns to within the
current bandwidth.
If the measured voltage is below 30 V, then the measured value is outside
the bandwidth and the relevant relay is also activated after 15 minutes. You
can deactivate this function if you want to avoid a function monitoring mes-
sage when the transformer is switched off:

Compensation
You can use the "Compensation" function to compensate for the load-de-
pendent voltage drop between the transformer and consumer. The device
provides 2 methods of compensation for this purpose:
▪
R&X compensation (line drop compensation)
▪
Z compensation
R&X compensation
R&X compensation (LDC) requires exact cable data. Line voltage drops can
be compensated very accurately using LDC.
To set R&X compensation correctly, you need to calculate the ohmic and in-
ductive voltage drop in V with reference to the secondary side of the voltage
transformer. You also need to correctly set the transformer circuit used.
