Xxxxxx Substation. The new communications equipment will be housed in the existing building and the new antenna mounted on the existing tower. The scope of work will include the following: Grounding: The grounding of the existing substation shall be inspected for adequacy, expanded to cover new installations, and the existing Control Building upgraded accordingly for a high frequency grounding system to safeguard electronic and telecommunication equipment from transient overvoltage as recommended by IEEE 1100 and Motorola grounding and Bonding Manual, R56.
Xxxxxx Substation. The Xxxxxx Substation WP-1 and WP-2 tap configurations will be each be converted to breaker and a half configuration. The conversion will require the addition of three circuit breakers, modifications to the existing structures, station connections, line terminations, and protection system. The existing 230kV 2100 bay will be modified by the addition of a third breaker to create separate terminals for the MW-2 and WRY-2 segments of the existing MWP-2 transmission line. PT’s and CVT’s will be added in conjunction with the line relaying modifications. A new 2300 bay will be added north of the existing 2200 bay in an area previously designated by Transmission Owner for expansion. The new 2300 bay will include two new 230kV circuit breakers, SF6 type, 2000A continuous circuit, rated 900kV, 63 kA circuit breakers, associated disconnect switches, and line terminal equipment to accommodate the relocated WP-1 transmission line. The WP-1 transmission line will be re-designated WPN-1. New PT’s and CCVT’s will be added in conjunction with the new line and relaying systems will be installed for the WPN-1 line. The MW-1 line will terminate in the 2200 bay. The existing MWP-1 line primary protection is a blocking carrier scheme using electromechanical relays with ON-OFF carrier equipment. The existing MWP-1 line secondary protection utilizes electromechanical relays to provide backup distance protection. New CCVT’s will be added in the 2200 bay. The existing Direct Transfer Trip is accomplished via audio tone equipment over single side band power line carrier channels. The existing primary and secondary MWP-1 line protection will remain and be re-designated as MW-1 line protection. The new equipment will include: - 230kV Circuit Breakers - 230kV Disconnect Switches - Potential Transformers - Capacitive Voltage Transformers - Primary Protection Panels - Secondary Protection Panels - Communication Racks - Termination Panels - Wave Traps and Line Tuners WRY-2 Line The primary line relaying will include: - Pilot Scheme; directional comparison unblocking (DCU) and primary direct transfer trip (DTTP) over power line carrier - New numerical multifunction relay for phase and ground fault protection - New FSK PLC equipment for DCU - Reconfigure existing FSK PLC equipment for DTTP - New hybrids - Additional auxiliary devices, test switches, lockout relays, etc. The secondary line relaying will include: - Pilot Scheme; current differential with secondary DTT (DTTS) over digital mic...

Xxxxxx Substation. The Xxxxxx Substation currently bisects the existing Greenbush-Xxxxxx Line 15 and Hudson-Pleasant Valley (Central Xxxxxx) Line 12 on the west side of the north-south right of way. With the removal of the entire north-south lines on the west side of the right of way (i.e., existing Lines 12 and 15), the Xxxxxx Substation will have to be tied to the new Xxxxxx-Falls Park Line 15 and the new Xxxxxx-Churchtown (Transmission Developer) Line 12. This will require modifications to protection and telecom at the Xxxxxx Substation.
