Gentlemen:
We are pleased to offer our proposal for the repair
of subject transformer.
WORK SCOPE:
1. Unload unit from customers transportation, perform
preliminary teats and .inspections.
2. Unload separately :shipped bushing and .inspect.
3. Disconnect any side bushings, remove cover and untank.
A. Joint itlopeetion of transformer damage.
S. Photonrapho of unit as found after untanking.
6. Remove }lead frame and ouperuLructure; unstaek top
core iron; remove coils for complete inspection.
Review and advise of damage and take photographs.
7. Clean and monger core, review and evaluate core
damage, if any is found. Repairs would be priced
as additional for customer's approval.
8. Perform computer analysis of existing design and
comparo to present standards required for improvins.
nhort: circuit withstand capabilities. Denif3n changes
will be submitted for customer review.
City of Denton
Page Two
9. All transformer designs will also be computer Uuulyzed
for impluse voltage distribution to verify that the
original design will moot present day standards. This
analysis gives the customer the opportunity to indontif y
original design deficiencies with our recommendations
for upgradeing.
10. All appropriate material associated with redesigned coils
and redesignod bracing will be new.
11. Wa will prnvi.de loss reduction options after performing _
our redesign engineering analysis. These options will be
priced ae additional and submitted for your approval prior
to proceeding.
12. Complete minor inspection of loud tap changing equipment
to include-
a- Draining, opening and flushing with the oil
tap changer compartment.
b. Visual examination of moving and fixed mechical
c>arta, such as shaft meals, bevel gears, stationary
and moving contacts, etc.
C. Tightness check on bolts, locking keys, pins, etc;.
d. Mechanical operation with the use of the hand crank
through all postions to check for binding.
o. Furnish and install now tap changer door moskets
as needed.
13. inspect all gauges and accessories for proper operation,
inspect and clean bushinsts and all C.T.'s within the tank
and all other auXiliarY windings within the tank will be
throughly flushed, cleaned, dried and tested. For LTC
transformers, this will include the :series tr•aneforater and
the preventive auto transformer.
14. Rewind all low voltage, regulating voltage & high voltage
coils.
City of Denton Page Three
15. Hydraulic leveling and dry leveling of all Coils to equal
height of radial spacer columns.
16. Process all coils through drying oven while maintaining
axial pressure on the coils. Thin process removes moisture
and further sizes the coils to designed dimensions.
17. Final sizing pressure applied and held until coils are
loaded on the core.
18. Reprocess core and coil assembly with trot oil spray
under vacuum in it's own tank.
19. Furnish and install new gaskets as needed for main tank.

on all tap connections.
c. Polarity and phase -relation test on the rated
voltage connections.
d. No load loss at rated voltage on the rated
voltage connection.
e. Exciting current at rated volatge on the rated
voltage connection.
f. Applied potential toots at 100% rated test
voltage.
g. Induced potential tests for 7200 cycles at
1009E rated test volatge.
h. Insulation powor factor tests.
i. Insulation resistance toots (megpor) on each
windinx and core.
21. One coat of ANSI No. 70 gray paint will be applied
22. Preparation and loading of the subject unit from
our facility.
23. Transformer will be shipped pressurized in dry air.
24. Transportation & new oil is not included in our base
price.

In line with currant government regulations regarding oil
filled transformers and possible PCB contamination "All
mineral oil filled transformers are presumed to be PCB
contaminated unless tests or other information prove
otherwise". All units being sent for repair must have the
oiul tested to determine possible PCB contamination levels_
Both the main tank and auxiliary compartments, such as LTC
compartments, must be cheoked separately. Test results
must precede the arrival of the transformer. Our proposal is
based on a Non -PCB transformer.
Our price for the rewind/redesign per our above

MEMORANDUM
TO:

City Manager
THRU:
R. E.
Nelson,
Executive Director of Utilities
FROM:
Ernie
Tullos,
Director of Electric Utilities
DATE: August 9, 1990
SUBJECT: HICKORY SUBSTATION TRANSFORMER FAILURE
On Monday, August 6, at 2:05 p.m., the Substation #2 transformer
experienced an internal fault and was disconnected by
differential relaying from the 69KV source and 13.2 KV main
feeders.
There was no interruption of service to our customers since we
were operating with both transformers in parallel.
The load on the station was reduced by transferring all, or
portions of the 13.2 KV feeders to adjacent substations.
Measurements were made of the internal windings of the failed
transformer, and it was determined that it would require
rewinding.
The failed transformer was manufactured in 1965 and is a 12/16/20
MVA unit with load tap changing for automatic voltage regulation.
It weighed 90,000 pounds with oil, and 60,000 pounds after
approximately 4,000 gallons of oil was removed for shipment.
Quotations were obtained from three bidders to rewind the unit as
follows:
1. Low Bid: Eastern Electric $ 98,740.00
Ft. Worth, Tx
2. Southwest Electric $103,041.00
Oklahoma City, Ok
3. Magnetek Ohio Transformer $108,000.00
Bradenton, Fla.
Page 2
Hickory sub
we accepted the low quote of the Ft. Worth, Texas company, and
shipped the transformer Wednesday afternoon. They now have the
unit to begin repair.
we did consider junking the unit due to its age (25 years), but a
new transformer would cost approximately $300,000 and would
require one year lead time. We decided that we could not operate
reliably since our only spare would be in service. When the unit
is disassembled, the shop may find that additional work/parts may
need to be replaced especially in the automatic tap changing
section. We expect to have the unit returned for reinstallation
in about 18 weeks.
We have processed a budget transfer in the amount of $130,000 to
cover all the expected cost, and have notified our insurance
carrier of the loss.
We have installed a spare unit that was purchased some five (5)
years ago expressly for this eventuality. It is a 28 MVA unit
compared to the 20 MVA faulted unit, and should be carrying load
with everything back to normal by Monday, August 13, 1990.
