Focus Partial Discharge

UHF Method Type PD Sensors

There are Partial Discharge Sensors & Noise Sensors used for the FPD Series. The Partial Discharge Sensors are classified as an External Sensor installed on the spacer of the GIS as well as an Internal Sensor installed inside of the GIS. In addition, there are various sensors which can be applied to multiple products like Transformers, Cables, MCSG, etc.
