Answer / s ghosh thakur

The following tests to be done during commissioning.
1.Duster value.
2.PI test The value should be above2.o
3.Tan delta test.
4.Ratio test.
5.short ckt.impedance test.
6.vector test.
7.IR test.
8.Polarity test. Thats are sufficient.

BDV value of TRANS OIL should not be less than 50 kv.
IR value of oil cooled trans should be 100M w.r.t gr.and HT
to LT also 100M.PI test should carried out value min 1.5 to
2.0

Answer / pinaki chatterjee

according to all routine test as per IS-2026 PART 1 and magnetic balance, also current balance test should be require if necessary temperature rise test can be made.

if the voltage level is 11 kv so IMPULSE TEST AS PER clause 12 can be made for better acivement.

partial discharge should always check
