Run-ZC8820 transformer tan delta tester has the function of insulation resistance measurement. The wiring method for measuring the insulation resistance is exactly the same as that of the dielectric loss measurement. The dielectric loss and the insulation resistance can be measured in one connection which significant improve test speed and reduce burden of test.
Let' see the Diagnostic testing for grounding systems video:
