Anti-interference insulation resistance tester is designed to evaluate the electrical insulation quality of large high-voltage transformers, motors, generators, long-distance power cables, tube bus and so on which are under strong interference of high-voltage substation and power plant on the scene. The tester has high output power (6-8mA), real-time voltage measurement (the actual charged voltage of the sample), leakage current measurement, and automatic discharge (discharge voltage measurement), which is particularly suitable for large capacitive test with over 110kv interference on the test site.
The optical digital insulation resistance tester is developed using the Faraday effect of magneto-optical crystal, IE660044.7 and IEC61850 to produce an optical digital insulation resistance tester:
1. Optical digital insulation resistance tester will not generate radiation and electromagnetic pulse, strong anti-interference ability and accurate measurement data.
2. Since the light is an insulator, the high voltage can be effectively isolated (to ensure the personal safety of the operator), and the accuracy and reliability of the sampled data are ensured while suppressing noise.
3. Can cope with its harsh test environment.
4.5.7-inch large screen display, actual test voltage display, leakage current display.
5. True automatic discharge function, no need to manually discharge.
6. Short-circuit current 10mA Strong anti-interference ability.
7. High output power of the instrument, real-time voltage measurement (actual charged voltage of the sample), leakage current measurement, automatic discharge (discharge voltage measurement)
8. Intelligent voice prompt function
Designed in strict accordance with safety standards, output voltage: 500v 1000v, 2500v, 5000v, 10000v.
