AI assessment
- T1.Meets
Does the offered transformer comply with vector group YNd11 per Sec. 3.1?
"Vector group: YNd11 — confirmed."
Vector group as specified. Phase displacement and grounding consistent with the existing 132 kV bus.
- T2.Meets
Are guaranteed losses within Sec. 3.5 tolerances (NLL ≤ 28 kW, LL ≤ 165 kW)?
"Guaranteed: 25.2 kW NLL / 153.5 kW LL @ 75 °C."
Losses are within spec. The bid offers best-in-cohort efficiency.
- T3.Meets
Bushing specification per Sec. 3.7 — is OIP (or RIS preferred) offered?
"Trench RIS HV / Pfisterer LV"
Bushing type aligns with Sec. 3.7 expectations.
- T4.Meets
FAT plan per IEC 60076-1 Sec. 10 with ACME witness points scheduled?
"FAT performed at FGH Mannheim per IEC 60076-1 Sec. 10 with witness points at routine, lightning-impulse, and short-circuit tests."
FAT scope and witness points consistent with ACME standard procedure.
- T5.Partially meets
Type test reports current and from an accredited lab?
"IEC 60076-1/2/3/5 type tests — RV-FGH-25-0044, FGH Mannheim, 2025-02-18."
Type tests cover -1/-2/-3 only. IEC 60076-5 short-circuit witnessed test is not on file.
This pack was drafted by Aria (, temperature 0.10) at the date and time stated above. Every claim contains a verbatim quote and source page reference from the vendor's bid PDF. Items where the source could not be matched to actual PDF content are shown as "Not Addressed" rather than rendered with an inferred citation, in line with ACME P-AI Procedure Sec. 4.
