is used in HT Transmission line in place of P.T.?

Answer Posted / anil kumar

hi
pottential transformers are in the one of the category of
induction trasformers.these are use to measure the voltage
at some particular level that is atmedium level.(see it is
exactly similar to the question why we use voltmeters
instaed of potentiometers)capacitor voltage transformer we
form series of capacitors that can stote(trasform)voltage
high levels.where pts are inductive type in nature

Is This Answer Correct ?    10 Yes 23 No
