Partial Discharges Registration in Transformer Oil at the ‘Point-Plane’ Electrode System

Abstract:

The results of the experimental studies of partial discharges in GK transformer oil with electrode system “point-plane” that provide sharp inhomogeneous electric field are presented. It was found out that two types of partial discharge pulses which differ in form and time duration appeared at the negative point polarity of the needle. The study of different types of pulses was conducted by electric and electro-optical methods of partial discharge registration.
