Inghams Station. The Transmission Owner will design and construct System Upgrade Facilities at Inghams Station, including line Relay Protection Packages associated with the addition of the Interconnection Station in the existing 115 kV Valley - Inghams #3 line. The following required detail modifications are associated with the #3 Valley-Inghams Line and the changes as a result of the #3 Line being split to accommodate the Fairfield Station. All modifications will adhere to NPCC Document A-5: Bulk Power System Protection Criteria. (1) A new POTT relaying system is recommended using the existing OPTIMHO relay to provide required primary pilot protection for the new line section. The communication medium will be either a leased telephone line, if available, or, if the leased telephone line is not available, another new power line carrier channel. (2) (2) The existing secondary relaying scheme of MDAR relay and the Blocking Carrier set (92.6 kHz) will remain. (3) New Power Line Carrier (PLC) frequencies will be added to accommodate additional PLC frequencies requirement. (4) Additional voice graded telephone circuits will be required if Audio tone based POTT scheme is selected. (5) DTT Transmit scheme and DTT Receive scheme with L/O relays will be added. (6) Existing No-Flow Scheme shall be studied by Planning Department with new recommendation(s) for the addition of the Interconnection Station.
