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 ...

Testing insulation is an important way to qualify a new installation. Testing also protects and prolongs the life of electrical systems and motors. Over the years, electrical systems are exposed to ...

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 In our previous issue, ...

Electrical insulation begins to age and thus deteriorate as soon as it is made. Exposure to harsh environmental conditions, such as extreme temperatures, mechanical damage, and chemical vapors, ...

In response to the growing recognition of the benefits of 15 kV dc insulation testing, Megger has introduced two new instruments with 15 kV testing capabilities – the MIT1525 and the S1-1568.

Because they are integral to a variety of common test applications, ensuring of high-Ω measurement accuracy can be critical High-resistance measurements are integral to a variety of test applications, ...

The new S1 Series of 5-kV and 10-kV insulation resistance testers from Megger are designed specifically to assist the user with the testing and maintenance of high-voltage equipment. The new S1 Series ...

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 ...
