Common use of Main Substation Transformer Clause in Contracts

Main Substation Transformer. (NOTE: If there are multiple transformers, data for each transformer should be provided. If final impedance data is not known at this time, the IC should supply typical data for use in completing the short-circuit portion of the System Impact Study (SIS).)  Rating (ONAN/ONAF1/ONAF2): / / MVA / MVA / MVA  Nominal Voltage for each winding (Low/High/Tertiary): / / kV / kV / kV  Winding Connections (Low/High/Tertiary): / / (e.g. Delta, Wye-gnd)  HV DETC (NLTC), LTC or None: Available Taps: Operating tap: kV  Impedances: HV-LV, HV-TV, LV-TV, assuming 3-winding design, in per-unit on transformer self-cooled (ONAN) MVA Base Rating:  Positive sequence Z1: HV-LV: R1: pu X1: pu  HV-TV: R1: pu X1: pu  LV-TV: R1: pu X1: pu  Zero sequence Z0: HV-LV: R0: pu X0: pu  HV-TV: R0: pu X0: pu  LV-TV: R0: pu X0: pu
