OMICRON's PDL 650 localizes the acoustic signals using multiple sensors spread out over the transformer. Partial discharges often occur due to impending insulation faults when electrical and acoustic ...

OMICRON announces the release of its new MPD TransformerTest Module for partial discharge (PD) testing on power transformers during factory acceptance tests. This optional software module provides ...

After three 4,160V dry type transformers failed at a 30-yr-old hospital over a three-year period, the hospital's facility manager contacted the transfomer's manufacturer, who informed him the ...

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 ...

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 ...

MV substations play a crucial role in the power distribution network, which means that substation failures are almost always costly and disruptive. There is a good case, therefore, for regular testing ...

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 ...
