Cabinets with PKUS SR24 Control and monitoring panel with event recorder for transmission and receiving 32 teleprotection and emergency control commands produced by Unitel Engineering LLC were installed at switching station Putkinsky

At the end of 2020, during the implementation of the project "the 3rd section of the 330 kV overhead line NPP Kolskaya – SS 330 kV Louhi – HPP Putkinskaya " (the project “switching station Putkinsky”), the following equipment manufactured by Unitel Engineering LLC was delivered:

- Cabinets with PKUS SR24 Control and monitoring panel with event recorder for transmission and receiving 32 teleprotection and emergency control commands;

- PKUS EO2 Interface converters.

Commissioning and testing of cabinets with PKUS SR24/32 and EO2 equipment were carried out, as well as checking the commands transmission with measuring the PKUS SR24 command transmission time via E1 links and direct fiber optic between switching station Putkinsky (distribution point 330 kV Borey) and distribution point 330 kV Kamenny Bor, as well as between switching station Putkinsky (distribution point 330 kV Borey RP) and SS 330 kV Louhi.

To check the commands transmission with the measurement of the command transmission time, the UTK8 teleprotection command tester manufactured by Unitel Engineering LLC was used.
