Earth Insulation Tester
For 10kV Professional Insulation Tester With Large Capacity
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
