GOZ-JFD Digital Partial Discharge Test Device
GOZ-JFD Digital Partial Discharge Test Device is designed for partial discharge measurement of transformer, motor, mutual inductor, cables CIS, switches, arrester and other electrical devices with using the world's most widely used direct method, bridge balance method and current pulse method.
1. Stability, high reliability. GOZ-JF-H systems detection method, the measuring circuit, technical performance parameters are in full compliance with GB7354-87 and ICE-270 partial discharge measurement standards.
2. The system is pulse peak indicating form test system, and has a computer program-controlled filtering, amplification, sampling, storage, and display. Data acquisition and test voltage are simultaneously.
3. Adopting digital window technology with anti-interference ability and dual-channel differential measurement and digital technology which can measure two test items or one test item for two measuring points partial discharge signals. It can easily analyze the source of partial discharge signals.
4．Friendly man-machine interface systems, full Chinese menu prompts, any storage and printing, automatically generated test report, two-dimensional or three-dimensional map display .
5．System is configured RLC detection impedance to measure the partial discharge pulse signal and inhibit experiments power frequency and other low-frequency interference signals.
