Digital detector partial discharge test and the sensorwith the software using advanced signal processing technology covering a wide range of statistical methods and graphical display mode and coming with highenergy lithium batteries can flexibly achieve the detection of transformer partial discharge signals and ultrasonic signals capable of full range of detection for the transformer's partial discharge.

Partial discharge detection location detect the partial discharge changes in the transformer's internal during the operation by examining the partial discharge conditions of the device to analyze the insulating state of the transformer.
