Comparison between piezoelectric and capacitive sensors for PD detection and signal monitoring in palm oil

High-voltage transformer is the most critical and expensive component in a power system network in order to ensure the stability of the system. Partial discharge (PD) detection is a technique widely used for high voltage equipment insulation condition monitoring and assessment. PD phenomenon causes...
