Notes,
1. Itbys bid far Iheae transformers contains astray losses amount that pushes the DOE calculated efficiency below the acceptable minimum of 99.16%. They also lake many exceptions to our specilkalic n. which "we accustomed to and are currently updating our spec. However, nd meeting the ambient
temperature design range will rat be accepted next lime around This bid is considered to not meet our specdoation
2. Waster's bid for ABB transformers appears to meet our specification
3. WUE's bid to Central Molorrey transformers appears to meel our specification
4. WUE's bid for CG units did not have the required stray kisses Information and as such is considered to be non -responsive.
5. W UE's bid for Howard transformers appears to meat our specfication
6. Whitefish Energy submitted a bid for a mamuladurer that is not on our approved list. There are also issues with the Information sent along with the bid such as the reference to IEC 60076 and the fact that the compartment dimensions ere no where close to what is required in IEEE C57.12 M. This is considered
a non -responsive bid.
Based on the ranking of the evaluated bids, Howard Industries (care of Western United) is the lowest evaluated responsible bidder and should be awarded the portion of Bid 8327 for 13-150 kVA transformers.
IEEE C57.12.00, Section 9.2 Tolerances for Impedance
The tolerances for impedance shall be as follows:
a) The impedance of a two -winding transformer with an Impedance voltage greater than 25%shall have a tolerance of 17.5%of the specified value, and those with an Impedance voltage of 2.5%or less shall have a tolerance of 110%of the specified value.
Differences of impedance between duplicate two -winding transformers, when two or more units of a given rating are produced by one manufacturer at the same Ume, shall not exceed 7.5%of the specified value.
b) The Impedance of a transformer having three or more windings, or having zigzag windings, shall have a tolerance of 11O%of the specified value.
Differences of impedance between duplicate three -winding or zigzag transformers, when two or more units of a given rating are produced by one manufacturer at the same time, shall not exceed 10%of the specified value.
c) The impedance of an autotansformer shall have a tolerance of110% of the specified value.Differences of impedance between duplicate aut transformers, when two or more units of a given rating are produced by one manufacturer at the same time, shall not exceed 10% of the specified value.
dl Transformers shall be considered suitable for operation in parallel when reactances come within Me limitations of the preceding paragraphs, provided that turns ratios and other controlling characteristics are suitable for such operation
