44 LOSS EVALUATION
Loss evaluations and loss costs will be based on no load losses at 25°C after
impulse and load losses corrected to 75°C The following loss values will be used
a) No load I e excitation losses at $3 955/kW
b) Load i e IZR losses at the base 55°C rating at $2,780/kW
c) Cooling losses at $1,000/kW
d) The ratio of load losses to no load losses shall not exceed 5 0 at the base
55°C rating
Transformers will be evaluated on excitation losses and IZR losses and cooling
load at the above specified rates If tested losses exceed quoted losses but are
within the tolerances of Table 13 ANSI C57 12 00-1973, the additional cost
incurred from the differential of losses will be calculated using the following
equation and the above specified rates and will be deducted from the original
Purchase Order or back charged to the Manufacturer
Excess loss $ - [No of units] [(No Load Loss Evaluations $) (Avg No Load
Losses - Quoted No Load Losses) + (CU Loss Evaluation $) (Avg CU Losses @
Max 55°C Rating Quoted CU Losses @ Max 55°C Rating) + (Cooling Loss
Evaluation $) (Avg Cooling Losses @ Max, Rating - Quoted Cooling Losses @
Max Rating)) If this equation results in a negative number, no credit will be
given the Supplier
If any unit or units exceed the tolerances of Table 13 ANSI C57 12 00-1973 that
unit or units may be rejected or if accepted the deduction for excess losses will be
based on the following equation Excess Loss $ = (No Load Loss Evaluation $)
(No Load Losses Quoted No Load Losses) But Not Less Than Zero + (CU Loss
Evaluation $) (CU Losses @ Max 55°C Rating -Quoted CU Losses @ Max
55°C Rating) But Not Less Than Zero + (Cooling Loss Evaluation $) (Cooling
