15kV DC Insulation Resistance Tester
Model: HIT-15
The Insulation Resistance test is a quantitative test, which
indicates the effectiveness of a product’s electrical insulation.
The main applications include cables, transformers, motors /
generators, circuit breakers and bushings.
The HIT-15 is designed for performing insulation resistance tests
up to 15 kV with a
50 TΩ maximum resistance. The HIT-15 offers DAR(Dielectric
Absorption Ratio) and PI(Polarization Index) measurement.
The HIT-15 is capable of measuring capacitance of test object from
10uf to 100nf.
12V rechargeable Li-ion battery is adopted for HIT-15, which offers
rapid charge from an AC source if the batteries are flat.
The HIT-15 has a full suite of test modes as well as on-board
memory and the ability to download data to a laptop.
IP54 weatherproof enclosure is designed for outdoor operation. The
HIT-15 unit is robust enough to protect the tester and eliminate
moisture and dust ingress.
