Ultra High Frequency Partial Discharge Tester for GIS : 1. Principle of UHF detection The lower frequency limit of UHF detection is more than 300MHz, and the upper limit is 1000MHz and above. Therefore, the interference caused by corona discharge, is eliminated and its anti-interference performance is the best.
