HT7051 has been developed to measure insulation resistance with test voltage programmable up to 5kVDC 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.) within BT.
The device allows carrying out tests in FIX (with fixed test voltages), ADJUST (programmable test voltage) and RAMP mode (programmable test voltage and application time with selection of 3 available ramp types) which define a kind of operation suitable for any situation. Measurement of parameters such as Polarization Index (PI) and Dielectric Absorption Ration (DAR), are duration tests which allow defining the quality of insulation. HT7051 is supplied with NiMH rechargeable battery with integrated battery charger, which allows for a remarkable duration when carrying out measurements, it is provided with internal memory for saving measurements and it is also possible to connect it to the PC to download the measured results. The whole structure has been inserted into a comfortable and resistant transport case, solid and safe for “on-site” use.
