10-35-110 kV oil circuit breakers at substations for modern vacuum and gas-insulated ones and will put 306 arc protection devices into operation. To improve the reliability of control current systems eight new low maintenance battery systems and DC control systems will be installed." />
This year under the program of improving the reliability of power equipment specialists of IDGC of Centre — Belgorodenergo division will replace 205 outdated
The program of improving the reliability of power facilities provides for a variety of activities to replace obsolete equipment at substations and on
To reduce the number of outages of bus bar sections, power engineers will replace 160 oil 10 kV circuit breakers with modern vacuum devices with microprocessor-based relay protection. The new equipment has a low fire risk and has the best features in terms of mechanical wear and number of switching cycles, a larger set of protection features and automation. The application of microprocessor-based relay protection allows at an early stage to identify a fault in the equipment, preventing its failure. To prevent damage to high-voltage bays of
In order to improve the reliability of the equipment power engineers will replace over 11 thousand insulators on
To improve the control current systems reliability it is planned to install eight new low maintenance battery systems and DC control systems at substations, which require virtually no maintenance and completely exclude the emissions of reactive elements in the environment.
320 current transformers of 10 kV and 30 transformers of
Deputy Director for Technical Issues — Chief Engineer of the branch Denis Yagodka stressed: “Our goal is reliable and uninterrupted operation of equipment, reduction of losses and high quality power supply to consumers”.
