what is mean by tan-delta tap in the potential transformer??
 Question Submitted By :: Electrical-Engineering
I also faced this Question!!     Answer Posted By  
 
Answer
# 1
Near the HT bushing on the top cover you can find it which
is covered by a plate.This is used for measuring Tan-delta

# 2
I have not heard about tan-delta tap but there is tan delta
testing of PT.It is used to measure the insulation resistance
between phases and between phase and earth and also IR values between in the bushings.
