3.3 LEGAL ADDRESS
The business address of the Seller given in the Proposal is hereby designated as the place
to which all notices, letters, and other communication to the Seller will be mailed or
delivered. The address of the Purchaser appearing in the Conditions is hereby designated
as the place to which all notices, letters, and other communication to the Owner shall be
mailed or delivered. Either party may change his address at any time by instrument in
writing delivered to the other party.
3.4 SCOPE OF WORK, INTENT OF CONTRACT DOCUMENTS, AND
QUALITY OF MATERIALS AND WORKMANSHIP

3.5 ASSIGNMENT OF CONTRACT
The Seller shall not assign the Contract or assign any monies due or to become
due to him under the Contract without the previous written consent of the City.
No assignment of this Contract by the Seller with the consent of the City shall be
valid unless it contains a provision that the funds to be paid to the assignee under
the assignment are subject to all the Seller's obligations under the Contract.
3.6 CHANGES
The City may at any time, without notice to sureties and without invalidating the
Contract, order in writing, changes, within the general scope of this Contract, in
any one or more of the following: (a) technical requirements; (b) method of
shipment or packing; (c) place of delivery; and (d) time of delivery. If any such
changes are ordered, the Seller shall modify the work accordingly and if there is a

Contract Price or Delivery Schedule, or both, by means of a Change Order
executed by the City and the Seller.
If a modification increases the amount of the work, and the added work or any
part thereof is of a type and character which can properly and fairly be classified
under one or more unit price items of the Proposal, then the added work or part
thereof shall be paid for according to the amount actually done and at the
applicable unit price. Otherwise, such work shall be paid for as hereinafter
provided.
Claims for extra work will not be paid unless the work covered by such claims
was authorized in writing by the Owner. The Seller shall not have the right to
prosecute or maintain either an arbitration proceeding or an action in court to
recover for extra work unless the claim is based upon a written order from the
Owner. Payments for extra work will be based on agreed lump sums or on agreed
unit prices when such prices are agreed upon before the extra work i s started;
otherwise, payments for extra work will be based on the actual direct cost of the
work plus a percentage allowance. The percentage allowance shall include the
Seller's extra profit and extra overhead and, unless otherwise agreed, the
percentage allowance shall be fifteen (15) percent of the total direct cost.
If a modification decreases the amount of work, such decrease shall not constitute
the basis for a claim by the Seller for damages or anticipated profits. Where the
cost of property, made obsolete or excess as a result of a change, is included in the
Seller's claim for adjustment, the City shall have the right to prescribe the manner
of disposition of such property.

Attention: Accounting Division, with copies to Mr. Hover's attention.
All invoices and correspondence shall show the City's Purchase Order Number.
4.4. 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. I2R 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 I2R 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
Losses @ Max. Rating - Quoted Cooling Losses @ Max. Rating) But Not Less
Than Zero.

4.5.2 EXAMINATION OF PRODUCT
Each unit shall be inspected to determine compliance with respect to dimensions,
material, workmanship construction and marking, and shall be given the
Manufacturer's standard preliminary tests.
4.5.3 CONTROL WIRING AND AUXILIARY EQUIPMENT CHECK
The control wiring, auxiliary cooling equipment and current transformers shall be
checked to verify all winding connections and proper operation of auxiliary
cooling and control functions. Current transformer ratios and polarities shall be
checked.
All control circuits shall be tied together and 1500 volts shall be applied for one
minute to verify proper insulation of the control circuits. Certain instruments and
relays may be excluded from this test because of limitation of their voltage
capability. All current and potential transformer secondaries shall be tested at
2500 volts.
The power requirements of the auxiliary cooling equipment (pumps and fans)
shall be measured for all stages of cooling. The WA and the real power (watts)
shall be measured and recorded during this test and compared to design and
guarantee values.
4.5.4 LEAK TESTING
The transformer shall be filled with oil and tested for air and oil leaks under (a) 4
psig vacuum for one hour, (b) 10 psig pressure for 8 hours.
4.5.5 RESISTANCE MEASUREMENTS
Hot and cold resistance measurements of all windings shall be made on the rated
voltage connection and at the tap extremes. Resistance measurements on other
than the rated voltage connection are only required on one unit if more than one
unit of the same design is produced by the same Manufacturer at the same time.
4.5.6 RATIO
Ratio Tests shall be made on the rated voltage connection and on all tap
connections. For LTC units, Ratio Tests shall be in accordance with paragraph
8.3.1 of ANSI C57.12.00-1987.
4.5.7 EFFICIENCY, LOSSES, AND IMPEDANCE
4.5.7.1 No -Load Loss Tests at rated voltage on the rated voltage connection and Exciting
Current Tests at rated voltage shall be made twice: once before Impulse Tests and
once after Impulse Tests. Results of No -Load Loss and Exciting Current Tests
made after Impulse Tests shall not exceed 1.075 times the results of those made
before Impulse Tests. These Tests shall be made at 100 percent and 110 percent of
rated voltage. 24
362-003
REVISION G - 2/21/2003
4.5.7.2 Impedance and load loss at rated current on the rated voltage connection and on
the tap extremes shall be measured for each set of windings at the OA rating and
corrected to 75°C. For LTC units, Impedance and Load Loss Tests shall be in
accordance with paragraph 8.3.2 of ANSI C57.12.00-1987. Impedance and Load
Loss Tests on connections other than the rated voltage connection are only
required on one unit if more than one unit of the same design is produced by the
same Manufacturer at the same time.
4.5.7.3 Zero phase Sequence Impedance Tests shall be made between all windings. The
positive and zero sequence impedances, reactances, and resistances corrected to
75°C shall be furnished by the Seller as part of test reports.
4.5.7.4 Efficiency at 1.0 power factor and 75°C shall be computed for 50 percent, 75
percent, and 100 percent at OA rating.
4.5.8 DIELECTRIC TESTS
4.5.8.1 LOW FREQUENCY TESTS
Low Frequency Tests shall include Applied -Potential and Induced -Potential Tests
of all windings including those of the series transformer if used. For the Applied
Potential Test, the 60 Hz voltage applied between each winding and all other
windings connected to core and ground shall be equal to the specified low
frequency test voltage and shall be applied for one minute. For the Induced -
Potential Tests, the specified low frequency test voltage shall be applied for 7200
cycles regardless of the test voltage frequency.
The transformer will be considered to have successfully passed the low frequency
tests if no appreciable amount of current flows in the test circuits during the
respective tests.
4.5.8.2 IMPULSE TESTS
Impulse Tests including Front -of -Wave Tests shall be made on all windings. The
Front -of -Wave Test is not required on the low voltage neutral.
The time to crest for the Reduced Full Wave Test may be determined as the time
elapsed between 30 percent and 90 percent of the crest magnitude multiplied by
1.67. Both voltage and current wave shapes shall be recorded (oscillograms) for
both Reduced Full Wave and Full Wave Tests. Copies of the oscillograms shall
accompany the test reports.

REVISION G - 2/21/2003
4.5.9 AUDIBLE SOUND LEVEL TESTS
Transformer noise level tests shall be conducted according to the provisions of
ANSI C57.12.90.
4.5.10 LONG TIME DIELECTRIC AND CORONA DISCHARGE
The intent of this test is to combine the Induced -Potential Test, Corona Discharge
Test, and Long Time Dielectric Test into one test.
Where applicable, the test equipment, instruments and test procedure shall
conform to Methods of Measurement of Radio Influence Voltage of High Voltage
Apparatus, NEMA 107-1964 (Reaffirmed 1976), except as covered by this
Specification. The measurement shall be made by coupling a radio noise meter to
the high -voltage terminal of the phase under test. The bushing capacitance tap may
be used to couple the noise meter to the high -voltage bushing. The measurements
may be made at any radio frequency between 0.900 and 1.100 MHz. The
weighting detector circuit of the noise meter shall have a charging time constant
not exceeding 12 milliseconds, and a discharge time constant of not less than 500
milliseconds.
A calibration procedure shall be established for each high -voltage bushing at the
frequency to which the noise meter is tuned to establish the ratio of voltage at the
high -voltage terminal to voltage read on the noise meter.
The test voltage frequency should be increased relative to operating frequency to
avoid core saturation. A test frequency of 120 Hz to 300 Hz is acceptable.
The transformer shall be excited from a three phase source and the test voltage
shall be increased, taking required measurements as necessary, to the low
frequency test voltage specified herein and held for 7200 cycles. In addition to the
measurement required for the Induced Potential Test, readings of RIV shall be
taken on each phase at 0%, 100% and 150% maximum* continuous operating
voltage and at full induced test voltage. Readings shall be taken both as the voltage
is increased and as it is decreased. After 7200 cycles the test voltage shall be
reduced to 150% maximum* continuous operating voltage and held for one hour.
Discharge monitoring shall be continuous over the one hour test period to insure
the transformer is free of damaging partial discharge in the insulation structure.
The transformer will be considered to have failed the corona requirements of the
Specification if radio influence voltages measured as described herein exceed
ambient by 190 microvolts at full induced test voltage, 150 microvolts at the one
hour test voltage, or 100 microvolts at maximum continuous operating voltage.
Other evidence of failure could include occurrences such as an indication of
smoke and bubbles, audible sound as a "thump", and a sudden increase in test

circuit current. Any such indication of failure should be carefully investigated
whether by observation or by repeating the test or by other tests, to determine if
failure has occurred.
*Maximum continuous operating voltage shall be defined by ANSI C84.1.
CORE INSULATION RESISTANCE TEST
The insulation between the core and the tank shall be checked using a 1000 volt
megger between the tank of the transformer and the intentional core ground
terminal. This test shall be done at the conclusion of the Induced -Potential Test
while the transformer is still filled with oil. The resistance shall be 1000 megohms
(corrected to 20°C) or greater after one minute of application of 1000 volts in
order for the transformer to pass this test.
WINDINGS FOR SERIES OR MULTIPLE CONNECTION
If units have windings for series or multiple connection, see tables I and II for
those tests that shall be made with both series and multiple connections. All other
tests shall be made with the connection producing the most severe condition for
which the unit is being tested.
INSULATION POWER FACTOR AND WINDING CAPACITANCE
Insulation power factor and winding capacitance shall be measured and reported.
The acceptable value for insulation power factor when corrected to 20°C, is 0.5%
for transformers and 0.55% for bushings.
SHIPMENT
Each transformer shall be filled with dry nitrogen for shipment. The transformer
and any components which are packaged separately shall be fastened to the freight
car so that they will not shift, tip, or drop during shipment. All freight cars used in
the shipment of the transformer and accessories shall be marked for careful
handling, and dieital impact recorders shall be installed on each freight car.
Transformers below 10 MVA maybe shipped oil filled.
The freight cars carrying the transformer and the accessories shall be shipped
coupled together. In addition, the Bill of Lading shall include the following:
"The transformer car number
accessories car(s) number _
together."
and

REVISION G - 2/21/2003
5.1 RAIL CAR DETENTION CHARGES
The supplier shall allow three days for transformer unloading upon notification
that the rail car has been placed at the designated rail siding. After unloading the
Owner will notify the Seller that the rail car is ready to be released. It shall be the
Seller's responsibility to notify the railroad that the car is ready for pickup and the
Seller shall be responsible for all detention charges due to lack of notification of
the railroad.
