Rosseti FGC UES is modernizing short circuit protection at substations in the Khabarovsk Territory and the Jewish Autonomous Region. Modern equipment will reduce the likelihood of damage to equipment at power facilities.

According to the Rosseti press service, work is underway at seven substations. The new equipment will affect power facilities that provide not only power supply to ordinary consumers, but also strategically important facilities, such as the Transsib substation.

About 31 million rubles were invested in the modernization project. Russian equipment of a new generation - fiber-optic arc protection - will be installed at seven sites. These devices react to flash of arc light and are therefore more sensitive than previous protection models. Previously installed protection systems were triggered by combustion products and insulation overlap.

As soon as the outbreak is fixed, the new protection systems will instantly give the command to turn off the devices. This allows you to localize the damage and save the equipment. The work is scheduled to be completed by the beginning of the 2021-2022 winter season.

At the first stage, work is carried out at the 500 kV Khabarovskaya substation - one of the key supply centers of the Far East, which is involved in the power delivery of the Bureyskie HPP cascade. The protection will also be installed at the 220 kV Londoko and Kuldur substations, which feed the Transsib substations and the federal health resort - the Kuldur sanatorium complex. The work will also be carried out at the 500 kV Khekhtsir-2 junction substation, and at the power facilities providing electricity to consumers in the Vanino region –220 kV Vanino and Vysokogornaya, and at the Lazo - 220 kV "Hydrolysis".
