In our previous issue, we described time-resistance and dielectric absorption ratio tests. Two other useful insulation resistance tests are the short time and step voltage tests. Short time. This is ...

Insulation resistance testing is one of the most useful predictive maintenance tests available. This test gives insight into the integrity of insulation. The higher the resistance across the ...

To meet the requirements of your electrical safety testing applications, you can choose from a variety of instruments and systems that perform hipot, insulation-resistance (IR), ground-resistance, and ...

Bringing the benefits of 15 kV DC insulation resistance testing to challenging environments such as HV transmission and distribution substations, Megger’s new S1-1568 test sets combine noise rejection ...

Measuring the electrical resistance (ohms) of motors, compressors, and other electrical devices in HVAC systems may seem straightforward. But when the measurements of zero (0) or “OL” (overload) come ...
