Experience in application of The COMPACS-RPE bench system with an integrated partial discharges sub-system in repair production of OOO MRP Gazpromneft Omsk Refinery

The article dwells upon the importance of timely control of asynchronous motor condition and the need to develop new methods of condition diagnostic of their main assemblies. Currently available test benches for electric motors usually control vibration, temperature, rpm and current consumption of an asynchronous electric motor(AEM). That ensures high accuracy of AEM mechanic assemblies’ condition assessment, but condition of AEM insulation in that case can be observed only indirectly.

A perspective new method of AEM stator winding insulation defect diagnostics is a partial discharges control method. A partial discharge is an electric discharge paralleling a part of insulation between different-potential electrodes. Partial discharges (PD) occur in insulation defects, inclusions, uneven parts, gaps between the insulation layers. Such spots with dielectric properties different from the main insulation’s properties cause redistribution of electric field which leads to occurrence of insulation parts with high strength of electric field. Multiple PD during machinery operation may have a negative influence on the insulation state and (if the PD are intensive enough) cause a defect growth , sometimes, to a dielectric breakdown, which may result in machinery breakage or accident.
