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

1. Loss Evaluation

For the purposes of tender evaluation the 132/33/11.5kV transformer losses will be capitalized, in the following manner: Transformers No-load loss (NLL) 3052 US$/kW at rated voltage Load loss (LL) 730 US$/kW at rated MVA and voltage 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.
