GDJF-2002 Pulse Current Method Partial Discharge Tester

Product Description

GDJF-2002 Pulse Current Method Partial Discharge Tester



Test method of GDJF-2002 partial discharge Tester: Pulse current method


The pulse current method is a classic method for partial discharge detection, following the IEC 60270 international standard.

It evaluates the insulation state of electrical equipment by directly measuring the instantaneous current pulses generated by partial discharge. This method is known for its high precision and quantitative analysis, and is one of the most widely used techniques in laboratory and field testing.
