Insulation resistance tester is a compact, high voltage output, battery powered testing instrument, can be used to measure the absorption ratio, polarization index insulation resistance test items.
Application places:
insulation resistance tester is to solve high voltage substations, powerplant site under strong interference for large high voltage transformer, electric motor, generator, a long power cable, tubular busbar and electrical insulation quality assessment and design, instrument power output is big, the real-time voltage measurement (try actually charged voltage), leakage current measurement, automatic discharge (discharge voltage measurement) is especially suitable for large capacitive try and 110 kv power interference of test site.
Strong anti-interference ability, single machine can resist AC2000 ac interference, will not damage the instrument.
Main Features
1. Design in strict accordance with safety standards, output voltage:500v 1000v,2500v,5000v,10kv,12kv.
2. AC2000V, 50mA induction current can cope with the harsh test environment.
3. 5.7 "large screen display, actual test voltage display, leakage current display.
4. Capacitance measurement function.
5. Short circuit current≥10mA.
6. Automatic calibration function of the instrument, automatic calibration accuracy before testing.
7. This instrument has the functions of live voltage measurement, leakage current measurement and automatic discharge for the actual samples. It can intuitively see whether the sag voltage of the test instrument with load meets the national requirements through the live voltage measurement function for the actual samples. In addition, the insulation condition of the sample can be directly seen through the measurement function of live voltage and leakage current of the sample.
8. It can automatically measure and remember the values of R15S, R60S and R10min, and display the polarization index (PI), inductance absorption ratio (DAR) test values and test time.
9. Excellent anti-interference performance, especially used in power system of 110KV and above large capacity transformer and long distance power cable.
10. Automatic discharge: the advanced high-voltage discharge technology is adopted to rapidly discharge the capacitive sample. When discharging, the discharge voltage is measured in real time (the test voltage of the sample is up to 0v). For the large-capacitance sample, manual discharge is required to ensure the safety of personnel due to the presence of the charge absorbed by the medium.
11. Internal rechargeable lithium battery power supply or ac power supply, real ac and dc dual-use does not affect the test accuracy.
12. The analog pointer coexists with the digital display, and the number reflects the accuracy of the insulation resistance of the tested product, and the analog pointer can reflect the dynamic change of insulation resistance during the test process.
13. Alarm function during voltage boost. The buzzer has alarm function when the device has high voltage output, indicating that there is high voltage output.
14. Battery quantity digital display and under voltage alarm protection function.
15. Intelligent battery charging management can effectively prevent battery life shortening or damage caused by overcharging.
16. Automatic shutdown function: this instrument has automatic shutdown function. It will shut down automatically 10 minutes after the End of measurement.
17. Short circuit protection, short circuit state will not burn the instrument.
