In order to increase the degree of electric power grid facilities utilization, to acquire the most comprehensive status data on the facilities, and to provide for efficient planning of maintenance schedule, the company’s specialists use the tools which enable to record corona activity in the ultraviolet spectral range. The presence of corona activity gives evidence of active energy losses, and as a consequence, of equipment faults.
IDGC of Volga, JSC, currently uses Uvolle tool to inspect power transmission lines and electrical equipment of substations. The tool was selected on the basis of the best ratio between its performance and price.
All data resulted from examination are being generalized, analyzed and used for planning and monitoring of repair and maintenance operations.
Apart from ultraviolet tools, IDGC of Volga also employs thermo-imaging and chromatographic solutions to perform diagnostics of electric power facilities.
