Tan Delta test kit rating
Tan Delta test kit rating
(OP)
1. Any one pl. suggest us that how to calculate the current rating of Tan-Delta test- kit for testing of 16.5kV, 260MVA Generator / 400/16.5kV 260MVA transformer (for both HT and LT).
2. For transformer bushing tan-delta testing, why should not inject rated voltage of the busing?
Advanced thanks,

2 –
2A - For one thing you are limited by the capability of your test set, generally 10kvac.
2B – For another thing you want to compare your results to other tests at standard voltage, generally 10kv or less.
2C - It's been awhile since I looked at the setup of the test taps. I remember there were two different varieties. If you did have the capability to put full line-to-ground voltage, you want to doublecheck to make sure you are not overstresing portions of the insulation system. Maybe someone else can refresh my memory on this.

I use 12 KV inductors in parallel with the gen/motor windings get my 100 mA TD kit up to 3 Amps.

Pl discuss regarding 2nd queiry.
Thanks...

Reason of selecting 2.5 kv may be availability of earlier bench mark values at that voltage.Some utilities have standardised at 10 kV.
