Abstract :
The suitability of radio frequency interference (RFI) measurements for the detection and identification of internal discharges occurring in instrumentation and distribution transformers was studied in terms of detect sensitivity, interference tolerance and useability. Different types of medium voltage transformers having various faults were measured in a high voltage laboratory and at an open area test site
