Some of these days a new transformer T-2 with the capacity of 80 MVA was put into service; it had been installed instead of the obsolete transformer with the capacity of 63 MVA. Within the framework of the investment program implementation in order to increase the reliability and capacity of the feeding center, the longitudinal coupling breakers 6 and 10 kV were also substituted, a new SF6 circuit breaker 110 kV with the modern microprocessing protection devices was installed.
