Transformer
The Transformer Rating fields to be completed as follows:
Transformer Rated primary voltage
: enter the nominal line-to-line
voltage (kV). Used to calculate I
HV
ref
. Both primary and secondary voltages
can be given as peak-to-ground (amplitude) or RMS. The right unit must be
selected from the associated drop-down menu.
Transformer Rated secondary voltage
: enter the nominal line-to-line
voltage (kV). Used to calculate I
LV
ref
.
Neutral type
: select from drop down menu with 2 options: “available”, “not
available”. If “available”, PD polarity discrimination is made available in
“System Configuration”, refer to the companion Intellix™ BMT 330 Service
Manual.
Power System frequency
: 50Hz or 60Hz. Used to calculate I
HV
ref
and I
LV
ref
.
Transformer type
: select between “single transformer” or “bank of 3
single phase transformers”. Used in the PD discrimination algorithm.
