Product Introduction
This product can be widely used in partial discharge detection of power system, including high voltage switchgear, ring network cabinet, voltage / current transformer, transformer (including dry type transformer), GIS, overhead line, cable and other equipment insulation state detection, through the following indicators to measure the discharge degree of electrical equipment:
Partial discharge intensity detection: by measuring the discharge signal in one power frequency cycle, the partial discharge intensity is characterized according to the maximum value (dB) in the discharge pulse sequence.
Partial discharge frequency detection: by measuring the discharge signal in one power frequency cycle, the discharge pulse is extracted and the partial discharge frequency is characterized according to the number of discharge pulses.

Product Feature And Application
- Configure different sensors to achieve partial discharge detection of almost all high-voltage electrical equipment;
- Provide time domain waveform, PRPD, PRPS and other discharge patterns to realize the analysis of different discharge types.
- Humanized man-machine interface facilitates data management of different devices;
- Built-in ultrasonic sensor and transient ground voltage (hereinafter referred to as TEV) sensor, which can be connected with special sensors such as transformers, GIS, overhead lines, cables, etc.;
- Adopts non-intrusive detection method, no need to power off during the test process, no need to configure additional high voltage source, it is more convenient to use than traditional pulsed partial discharge detector;
- The test bandwidth range is 30kHz ~ 2.0GHz, which is suitable for detection principles of various frequency bands.
