Modernization of equipment is the key to reliable operation of the power system.

Every year, work is carried out in the electric grid branches of RUE “Vitebskenergo” to replace obsolete and physically worn equipment at 35 / 110kV substations. During overhauls and reconstruction of the energy sector, oil circuit breakers are replaced by more reliable vacuum circuit breakers.

In total, the specialists of the Vitebsk energy system in 2018 installed more than 70 modern vacuum circuit breakers at substations. Their advantages are simplicity of design, high switching wear resistance, fire and explosion safety, and the absence of environmental pollution. Vacuum circuit breakers are easy to operate. Replacing obsolete oil circuit breakers with new vacuum ones, first of all, increases the reliability of power supply to consumers, reduces the likelihood of emergency and pre-emergency situations.

Together with the replacement of high-voltage equipment, new relay protection and automation devices are also installed, DC and AC cabinets, rectifiers, batteries and other modern equipment are being replaced.
