Common use of Upgrading the Erie St Clause in Contracts

Upgrading the Erie St. 115 kV Substation Terminal to Depew The Transmission Developer will upgrade the Erie St. line terminal for line #921, so that the line rating of 125/152/181 MVA (Normal/LTE/STE) is not limited. This work will include the following major electrical and physical equipment: Replace existing oil breaker 92142 with a new 145 kV, 3000 A, 63 kA, 650 kV basic insulation level (“BIL”) sulfur hexafluoride (“SF6”) breaker; equipped with 2 sets of 2000:5 multi ratio (“MR”), C800 current transformers (“CTs”) on each bushing, and 1 set of 1200/5A single ratio (“SR”), 0.15B1.8, RF 1.5 metering CTs; Replace existing breaker foundation with new 115 kV breaker foundation; Install one (1) new 121 kV coupling capacitor voltage transformer (“CCVT”), which replaces the existing bushing potential device (“BPD”) located on existing breaker; Install CCVT structure and foundation; Install CCVT junction box; Install grounding materials; Install conduit; control cabling; and Install bus work. This work will include the following major protection and control equipment: Replace existing breaker failure electromechanical relay package with one (1) SEL-451 bay control relay; Replace existing system A electromechanical relay package with one (1) SEL-411L system A line protection relay; Replace existing system B electromechanical relay package with one (1) GE-L90 system B line protection and system B breaker failure relay; Install nine (9) ABB FT-19R test switches; Install three (3) 19” rack mount adapter plates; Install a GPS clock for time synchronization; and Install a new communication processor for new microprocessor relays. There will be no modifications to the existing communication system (leased telephone line) and the RFL GARD 8000 equipment for Line 921.
