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 ...

Power cables are important assets in electric utility transmission networks for the reliable operation of power systems. To prevent catastrophic failures in underground cables and terminations, it is ...

What is partial discharge? Methods for measuring PD. How PD impacts high-voltage cables. Partial discharge (PD) is evidence of a degrading insulation system, which could trigger costly repairs and ...

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 ...

The new PD-SG1 first-level partial discharge detection instrument makes distinguishing between PD and electrical noise easy. Designed for use both in distribution voltage substations and EHV ...
