we have 400kv/6.6kv transformer ,it has total 9 taps on HV
side with normal tap on tap no 5.when we took the ratio
test we observed that ratio was decreasing from tap 1 to
tap 5 and was found increasing from tap 5 to tap 9.What is
the reason?if anyone have related document then please send
me on the email id ankushbahale@gmail.com......plz plz
