Kyoritsu’s 3128, a standardised 12KV insulation testing
By EPR Magazine Editorial July 5, 2019 12:55 pm
Kyoritsu range of insulation testers features more than 20 diverse models, with test voltages ranging from 15V to 12KV, and analogue or digital indicators. Battery-powered, compact and user-friendly, each and every product is an industry standard today.
Kyoritsu’s 3128 is defacto standard in 12KV insulation testing. They endeavour to provide the best in testing of insulation resistance with 6 test range.
Key features of 3128 are:
Microprocessor controlled high voltage insulation resistance tester with Diagnostic functions
Suitable for analysing the insulation characteristics of cables, transformers, motors, generators, high-pressure switches, insulators, wiring installations, etc.
6 ranges: 500V, 1000V, 2500V, 5000V, 10000V, 12000V. Fine adjustment of voltage setting at each range is also possible.
Graphic representation of the insulation resistance and leakage current versus time on large display with bar graph and backlight
Can be operated from built-in rechargeable battery or from AC line
Automatic discharge after test with monitoring of the discharge voltage
Internal memory can store about 43,000 data (max)
Robust design for field use with IP64 rating (with lid closed)
