The effective earth resistances R
the transformation ratio of the voltage trans-
former must be calculated in accordance with
the Operating Instructions.
Further details about settings of the various
functions can be obtained from the REG216/
316*4 data sheet.
Rotor earth fault protection
This function incorporates an alarm as well as
a trip level with separate tripping and signal-
ling outputs.
The function allows the measurement of the
actual coupling capacitance while the ma-
chine is standing still. This measurement per-
mits optimum settings with respect to the pro-
tected machine.
Alarm and trip levels are entered and read out
in kΩ.
