The present qualification system serves as the prequalification for the supply of grounding transformers for the medium‑voltage network (10-30 kV). It ensures that all potential suppliers comply with the technical requirements of our specification as well as the commercial and procedural criteria necessary for approved supplier status.
Lot 4 - NPB 30 kV / 280 A This lot covers a Grounding Transformer (NPB) with the following main characteristics: Vector group ZN, cooling type ONAN, designed for short-term operation of 2 hours. The rated high-voltage level is 31,5 kV with a rated current of 280 A. The specified zero-sequence impedance is 10.5 Ω per phase. All applicable requirements shall comply with DIN IEC 60076.
Lot 1 - NEB 10 kV / 350 A This lot covers a Grounding Transformer (NEB) with the following main characteristics: Vector group ZNyn5(d), cooling type ONAN, designed for short-term operation of 2 hours. The rated high-voltage level is 10.4 kV with a rated current of 350 A. The rated low-voltage level is 0.4 kV with a rated power of 400 kVA. The specified zero-sequence impedance is 3.5 Ω per phase. All applicable requirements shall comply with DIN IEC 60076.
Lot 2 - NEB 20 kV / 800 A This lot covers a Grounding Transformer (NEB) with the following main characteristics: Vector group ZNyn5(d), cooling type ONAN, designed for short-term operation of 2 hours.
