BY2677E Insulation resistance tester is designed and developed to evaluate the electrical insulation quality of large-scale high-voltage transformer, motor, generator, long-distance power cable, tubular bus and other electrical insulation quality under strong interference in high-voltage substation and power plant. It is especially suitable for the test site with large capacity and strong interference above 110kV.
Features
1. Wide voltage range: 1KV,2.5KV,5KV,10KV
2. Can test up to 2TΩ insulation resistance
3. 3½ LCD digital display of insulation resistance value
4. Auto shift resistance measuring range
5. Environment temperature can be measured
6. Self-clocking function, short buzz every 15 seconds
7. Auto calculate and save R15S, R60S, R600S, DAR and Polarization Index
8. Output short-circuit current≥3mA which meets fast charging request to capacitive load
9. Strong anti-interference ability, stable and reliable reading
10. Perfect protection, safe for operation
11. Powered by rechargeable Li-battery, auto power off when battery energy is not enough.
