HT7052 has been developed to measure insulation resistance with test voltage programmable up to 10kVDC and measuring range up to 10TΩ which makes it very useful in any industrial application (tests on electric machines, power transformers, electric cables, electric boards, generic devices, etc.).
The device allows measuring parameters such as Polarization Index (PI) and Dielectric Absorption Ratio (DAR) and Dielectric Discharge (DD), diagnostic tests which allow determining the quality of an insulating material. It carries out “ramp” insulation tests and dielectric strength test in DC.
