Summary
Project consists of high voltage preventative maintenance on the 26. 4kv and 5kv electrical distribution system on the university's campus. The electrical power system at University is fed from two (2) 26.4 kV utility services from PSE&G and extended to the outdoor main substation. The substation transformers T-1 and T-2 are outdoor oil filled type, and rated at 12/16/20 MVA, with primary voltage 26.4kV and secondary voltage stepped down to 4,160V. Feeder buses from each of the secondary side of the transformers, T-1 and T-2 are extended to indoor 4.16kV switchgear, listed as bus section "1" and bus section "2". Buildings located on the University Campus are fed from feeders derived from the 4,160V switchgear, located within the main substation/transformer compound. Each building has its own medium voltage double selector switch feeding (A/B Switch) an outdoor or indoor step-down transformer. Through a series of duct banks and manholes, each medium voltage selector switch is fed by two (2) 4,160V radials – originating from two (2) circuit breakers located in the main substation – listed as bus section "1" and "2".
