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 ...

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 ...

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 ...

Solid-state ac supplies replace motor-generator and tap-changing transformers to offer the same tests at the push of a button • Solid-state ac-power sources combine the variable-frequency and ...

Everyone knows that Thomas Alva Edison invented the lightbulb; but who invented the transformer - perhaps the most important electrical machine ever developed? The ZBD model alternating-current ...
