Handheld Partial Discharge Inspection Instrument Partial discharge phenomena of the electrical equipment have different impacts on equipment itself and the power grid, seriously leading to equipment scrapped and grid collapse. So it plays an essential role to monitor partial discharge of electrical equipment early, master the equipment running state accurately, eliminate the problems existing in the equipment timely and effectively for ensuring the safety of the equipment and the power grid itself. There are many ways for electrical equipment PD test, such as pulse current method, DGA method, ultrasonic method, RIV method, optical method, radio frequency method and chemical method, etc.
