GUARANTEED TRANSFORMER (AND REACTOR) LOSSES AND PENALTIES
The Tenderer shall complete the following guarantees based on highest declared rated power at Site conditions.
400/138.6/11kV, 250/250/75MVA, auto transformer (comprising 3x83.33MVA single phase units) as specified. Item Description
Unit Declared value
1 No load losses (NNL) at rated voltage ratio at IEC rating
kW
2 Load losses (LL) at 75°C and rated ONAF power and principal tapping: HV/LV winding at IEC rating
kW
3 Total losses (TL=NNL+LL) kW
250 MVAr 400kV Shunt Reactors where specified
Item Description Unit Declared value
4
No load losses (NNL) at rated voltage ratio at IEC rating
kW
5 Load losses (LL) at 75°C and rated ONAF power and principal tapping: HV/LV winding at IEC rating
kW
6 Total Reactor losses (TL=NNL+LL) kW
1. Loss Evaluation
For the purposes of tender evaluation the 400/138.6kV transformer (and where applicable the 400kV reactor) losses will be capitalized, in the following manner: Transformers No-load loss (NLL) 2932 US$/kW at rated voltage Load loss (LL) 688US$/kW at rated MVA and voltage Reactors No-load loss 2932 US$/kW at rated voltage Capitalisation (PV) Price capital value + NLL + LL
M.2 400kV GIS SUBSTATION – VOLUME 3
2. Penalties A maximum variation of +10% of the total declared losses (TL) is permitted. Any transformer or reactor with losses more than +10% of the Total Loss (TL) declared will be rejected, unless otherwise agreed by the Engineer. For transformers or reactors with total losses within +5% of the declared losses no variation of the contract price will be made. For transformers or reactors where the total losses are between +5% to +10% of the total declared losses the contract price will be reduced by the total capitalised cost of losses in excess of the capitalised cost of the declared guaranteed losses. For any transformer or reactor with total losses less than 100% of the guaranteed losses, no variation of the Contract price will be made.
