EQUIVILENT FIRST COST (EFC) EVALUATION
7.1
The vendor shall state all exceptions to this specification. If no exceptions are taken, vendor shall so state.
7.2
Equivalent First Cost (EFC) will be calculated and evaluated for all bids received. The method used to
determine the EFC is documented in A Method for Economic Evaluation of Distribution Transformers,
published by the Edison Electric Institute, April 1981.
7.3
The EFC shall be determined with the following formula:
EFC ($) = [4.81 x NLL (watts)] + [2.10 x LL (watts)] + Purchase Price
where NLL= No Load (core) Losses and LL = Load (winding) Losses.
7.4
All bidders shall supply No Load, Load and Total losses reported in watts on the form provided in the bid
documents. No load losses shall be reported at 20C. The value for load losses shall be corrected to 85C.
7.5
Quoted losses shall be the guaranteed average of all transformers in a specific order of a given size and type.
The losses of an individual unit in the shipment shall not exceed the tolerances specified in Table 19, ANSI
C57.12.00 - 10% No Load, 6% Total Load. Units exceeding these limits shall not be shipped to College Park
Power. If any such unit is found to have been shipped, College Park Power will request full credit based upon
the purchase price of the unit.
8.0
PENALTY FOR NON-CONFORMING TRANSFORMERS
8.1
Should any transformer fail to conform to the specifications in any way, then, at the option of College Park
Power, the vendor shall replace the non-conforming transformer with a suitable transformer and bear all
associated costs; or have the initial bid price reduced by a penalty charge calculated in accordance with
Section 8.2 below.
8.2
Calculation of the penalty charge in dollars per unit shall be the "Equivalent First Cost of Actual Losses" less
the "Equivalent First Cost of Quoted Losses."
8.3
In the event that a given order does not exceed the average losses as quoted, but any individual transformer
exceeds the tolerances as specified in Section 7.4, then the penalty charge shall be deducted from the bid price
of that unit.
Original 12/28/00 Rev. 1.1 7/30/03
5
Technical Specification for Dead Front Three Phase Padmounted Distribution Transformers (continued)
8.4
In the event the average losses for a given transformer order exceeds the quoted average, then the penalty
charge shall be calculated in accordance with Section 9.2 based on the difference of the actual average losses
and the quoted average losses and shall be deducted from each unit in the order.
8.5
In no case will the penalty charge exceed the bid price of the non-conforming unit.
9.0
PACKAGING AND SHIPPING
Each transformer shall be fastened to skids or to a two-way entry, disposable pallet of the vendor's own
design. This pallet must be of such dimension as to provide two inch (2") clearance of the transformer at its
widest outside measurements, on all four sides. Skids or pallet must provide a minimum of 2-1/4 inches of
fork underclearance.
10.0 WARRANTY
10.1 The vendor shall guarantee the transformers for a minimum period of 18 months from shipment or 12 months
from installation that all equipment covered by this agreement is to be free from defects in material and
workmanship. Any defective units discovered or identified during this period shall be replaced or repaired by
the vendor at no cost to College Park Power. Vendors are encouraged to provide extended warranties for the
entire transformer or for specific parts and/or performance (i.e., additional warranty on paint finish.)
10.2 Any material repaired or replaced under the terms of the above guarantee shall itself be covered by those
terms as if it were a new product.
10.3 The vendor shall state the expected service life and failure mode of the product in its intended application.
This should also include documentation explaining how expected service life was determined.
10.4 Any transformers that fail after the warranty, but before the expected service life, may be subjected to an
engineering failure analysis to determine the cause of failure. This analysis will be performed by the vendor
and College Park Power engineers. The vendor shall, if requested, supply the required resources for the
analysis at no cost to College Park Power.
