B :
1. BSE submitted two different drawings: one with lower weights and o8 amount, the other with higher amount. Are they submktp DOE 2010 and 2016. If ao, 8 has not been labektl as such.
2. Irby's quotation Includes an older Cooper drawing Mat does not show the specified IFD.
3. Weren't bid submittal did not'hdiude any drawngs or Dart list: we have to assume that May are hDMfd in starves the WOMct meate area cadan.
4. Western United submitted two designs from Howard: one labeled 5 % (HL-703) for a cheaper price and one labeled silicon (HL-7W 3) for more experobe. What does the 5% mean?
5. Western United submitted a quote for Central Moloney but wthout drawkgs. We have to assume Mat May are truthful in stating Mat May meet spec.
Based on the ranking of Me evaluated birth. Central Moloney care of Western Umled k Me lowest evaluated responsible bidder and should be awarded Bid 8058
IEEE 67.12.0%Session 9.2 Tolerwuea for impedance
The tolerances for Impedance shall be as (allows:
a) The Impedance of a two -winding transformer with an impedance voltage greater than 2.5%shall have a tolerance of 11,75%of the speafied value, and those with an impedance voltage of 25%or
less shall have a tolerance of t1M of the specified value.
Differences of impedance between doplkate two -winding transformers, when two or more units of a given rating are produced by one manufacturer at the same time, shall not exceed 75%of the
specified value.
b) The impedance of a transformer having three or more winding; w having zigzag windings, shall have a tolerance of t10%of the specified value.
Differences of impedance between duplicate three -winding or zigzag transformem, when two or more unks of a given rating are produced by one manufacturer at the same time, shall rest exceed
10%of the specified value.
c) The impedance of an autotransformer shall have a tolerance of t10%of the specified value. Differences of impedance between duplicate autotransformers, when two or more units of a given
rating are produced by one manufacturer at the same time, shall not exceed l0% of the specified value.
d) Transformers shall be considered suitable for operation in parallel when reactances come within the limitations of the preceding paragraphs, provided that turns ratios and other controlling
characteristics are suitable for such operation.
