Deep specs

  • Impedance: Indicative - GSU %Z and LPT %Z set independently per OEM; package RFQ must state interchange intent (GSU parallel vs LPT dual-feed) separately
  • BIL: Indicative GSU 345/gen-LV BIL + LPT 345/MV BIL per one-line; confirm campus HV class
  • Cooling: ONAF both legs typical; confirm ODAF on large GSU block. Cooling redundancy per equipment class.
  • Standards: IEEE C57 + IEC 60076 dual-path on both legs. Package adds pursue-order AVL evidence binder (eligibility companion - not proven-on-AVL).
  • Bushings: Package spans gen LV bushings (GSU) + HV interconnect bushings (LPT). Separate BOM/spare kits; HV bushing LT often package critical-path risk.
  • FAT: Indicative - FAT per leg; package ship may stagger. VERIFY labels close per serial/unit. Deposit companion is not draw-gate.
