Partial Discharge Localisation in Power Transformer by UHF Technique
High Voltage, Volume 10, Issue 5, Page 1314-1323, October 2025.ABSTRACT This article deals with the methods of finding partial discharge (PD) location in power transformers using ultra high frequency (UHF) measurements. The UHF technique utilises two methods to find the PD location, that is, the shortest path method and hyperbolic method.
