A new hyper-scale data center was built in rural New Jersey that’s served by more than 100 25kV cables. Six months into operation, a cable termination failed catastrophically, and the forensic ...

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 ...

Hipot testers are used to measure the leakage current and insulation resistance between all components and connections, verify solid ground connections, and test ground bonds. These tests include the ...

The measurement engineer can view the values from tan δ and partial-discharge testing directly in the cable test van. Clear representation helps to detect severe defects or locate partial discharges ...

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 ...

The street scene shows damage caused by an explosion in a manhole as a result of gases generated by a low-voltage arcing fault. North America, according to statistics published by the IEEE Insulated ...
