outgoing feeders from GPP-2 and opposite main step-down substations on
the territory of the oil-refinery.

panels; design of new fiber optic connections to provide operation of
the relay protections; substitution of oil-insulated measuring transformers at
110 kV outgoing feeders and coupler breaker with new SF6 measuring transformers.
