APM uses ultrasonic and electric power using DSP digital processing technology,measuring two kinds of online partial discharge detection technology, the ultrasonicsensor (AE) and high frequency current sensor (HFCT) for electrical equipment in the PD signals detection, analysis and fault location. The device can be widely used in power transformer, GIS, circuit breaker, cable and other electrical equipment of partial discharge (PD) charged detection, and through the networkinterface, remote communication to the substation and the control room.

Product features:

1, continuous on-line monitoring, detection, and fault analysis, has the very bigsignificance to discharge trend tracking

2, a machine to realize two kinds of technology that is at the same time using AE(ultrasonic sensor) and HFCT (radio frequency current sensor)

Detection sensitivity of 3, ultrasonic PD sensor sensitivity: 10pC, frequency CTpartial discharge sensors: 5pC

4, the test software on PD signal: waveform measurement, analysis, display andfault location

5, reliably prevent transformer, GIS, cable and circuit breaker due to the catastrophic failures caused by the internal insulation defect

6, the site easy to use: a portable and frame type two user selectable, instrumentwith self checking function
