IDGC of Centre - Voronezhenergo division, as part of the investment program implementation, works to increase the automation and observability of 10 kV distribution grids. It assumes, in particular, installation of new high-tech devices - reclosers, controlled disconnectors with a motor drive and fault locators, which record short-circuit current and earth fault current in overhead power lines. This will allow to isolate faulty sections and not to disconnect the whole line.
In 2018, the power company will install two reclosers and several dozens of controlled disconnectors and fault locators for 10 kV overhead power lines in Novousmansky and Ramonsky districts of the Voronezh region. More than 7 million rubles will be allocated for these purposes.
Reclosers allow to automate the process of locating and isolating faults in overhead lines, transmitting online messages about technological violations to the dispatcher, as well as providing automatic input of backup power. Their use makes it possible to minimize the time of interruptions in the supply of electricity in the event of emergency situations and significantly increases the level of reliability of power supply to consumers. Reclosers have been installed in the Voronezh branch of IDGC of Centre for several years. Currently, more than 30 such devices are already operating on Voronezhenergo’s power lines.
