Diagnostics and an on-load operation algorithm of high-speed voltage regulators

Diagnostics methods are considered of single- and three-phase high-speed switching units, such as of the PC and PNOA series, mounted on 35- to 330-kV power transformers. The diagnostics is carried out using a multichannel digital oscilloscope without opening the contactor tank and draining the diele...

Description
Summary:Diagnostics methods are considered of single- and three-phase high-speed switching units, such as of the PC and PNOA series, mounted on 35- to 330-kV power transformers. The diagnostics is carried out using a multichannel digital oscilloscope without opening the contactor tank and draining the dielectric liquid from it. Algorithms for automated determination of working capacity of switching devices are presented. It is revealed that the developed algorithms make it possible to shorten the time for preparing and obtaining the oscillograms of currents and automatic processing of measured values, automate the determination of working capacity of switching devices, record the diagnosing results in print, and create a database in digital form.
