HZJY-10K-Z Insulation Resistance Testing Unit insulation resistance test set of transformer


High-voltage insulation resistance tester, with 5 range: 500V, 1000V, 2500V, 5000V, 10000V, test up to 20TΩthere is also a manual boost function.

● design in strict accordance with safety standards

● insulation resistance range: 20t Ω @ 10KV

● the short-circuit current can be adjusted up to 3mA.

● automatically display the test values of polarization index (PI), absorption ratio (DAR), leakage current and capacitance, dielectric discharge test (DD) and step voltage test (SV).

● excellent anti-interference performance. When the interference current reaches 2mA, the instrument still ensures the test accuracy.

● AC and DC voltage test function of the tested line to automatically identify AC or DC.

● the capacitive test object discharges rapidly. During cable test, there is no need for manual discharge, and the instrument discharges rapidly automatically.

● two power supply modes: Powered by lithium battery, the endurance time can reach 6 hours.

At the same time, it can be charged in use. In case of power failure, it can automatically convert from AC power supply to battery power supply.

● the operation is simple and clear, and the insulation resistance analog column can be displayed.

● digital filtering function. When the displayed value deviates due to external influence, the filtering function is used to reduce the influence.

● perfect protection function and prompt function for fuse burnout.

● data saving function and data export.
