9 LOSSES
The total losses of a transformer shall be the sum of the excitation losses and the load losses (12R losses). Load
loss tests shall be performed and reported on all units regardless of whether or not a record of such tests is
available on duplicate units. Loss evaluations and loss costs will be based on the values shown in the "Special
Conditions and Supplemental Instructions to Bidders." Transformers will be evaluated on excitation losses and 12R
losses at the specified rates. If tested losses exceed quoted losses but are within the tolerances of paragraph 9.3,
ANSI C57.12.00-2000, 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. In the following equation "Units' shall mean "Transformers of the same size and
design on one order."
Excess loss $ = [# of units] [(No Load Loss Evaluation $) (Avg. No Load Losses - Quoted No Load Losses) + (Load
Loss Evaluation $) (Avg. Load Losses - Quoted Load Losses)]. If this equation results in a negative number, no
credit will be given the Supplier.
If any unit or units exceed the tolerances of paragraph 9.3, ANSI C57.12.00-2000, that unit or units shall not be
shipped'wlthout express permission from the City. 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
+ (Load Loss Evaluation $) (Load Losses - Quoted Losses) But Not Less Than Zero.
