I wonder if anyone can help me
I am trying to obtain generic errors for a metering 33Kv metering VT to satisfy the meter operator.
The original errors have been mislaid by the manufacturers and I require a copy of typical errors for a similar VT
Details are below:-
Manufacturer = AEG
Type EY36TAW1
Burden 60Va
Class 0.5
to IEC standard 186
Ratio 33000/110V
If someone can help with this query than that would be great
Thanks and Merry Xmas all
Viv.

A class 0.5 VT should have the voltage within +/- 1% and the phase within +/- 40'

My Areva NPAG manual gives a class 0.5 VT as +/- 0.5% accuracy with a +/- 20 minute displacement for a burden of between 0.25 and 1.0 at 0.8pf.

I believe IEC 60044 is the series for instrumentation transformers with part 2 being for inductive voltage transformers and part 5 for capacitive voltage transformers

Kind regards
