3.0 REQUIREMENTS
3.1 GENERAL REQUIREMENTS FOR DESIGN
3.1 1 BASIC DESIGN STANDARDS
Transformers purchased under these Specifications shall be new and,
unless otherwise specified, meet the requirements of the applicable
ANSI Standards and the modifications and additions given in the
subsequent paragraphs In case of conflict, the requirements of the
following documents shall apply in the priority shown:
a) This Specification
b) ANSI C57 12.26
c) Other applicable ANSI and NEMA Standards
3 1 2 KILOVOLT -AMPERE TEMPERATURE RATINGS
Kilovolt -ampere ratings are continuous and are based on not
exceeding either a 65°C average winding temperature or an 800C hot
spot temperature rise The temperature rise of the insulating oil
shall not exceed 650C when measured near the top of the tank The
temperature rise is based on an altitude of 3,300 feet
3 1 3 GENERAL CONSTRUCTION
3.1 3.1 The pad -mounted compartmental -type transformers shall consist of the
transformer tank, high -voltage cable terminating compartment, and
the low -voltage cable terminating compartment. All three of these
components shall be assembled as an integral unit, tamperproof and
weatherproof for mounting on a pad. There shall be no exposed
screws, bolts or other fastening devices which are externally
removable, except the main cover bolts may be exposed Where the
main cover bolts are exposed, the corner bolts shall be welded or
otherwise rendered tamperproof There shall be no opening through
which foreign objects such as sticks, rods, or wires might be
inserted to contact live parts Suitable means for padlocking the
compartment door(s) shall be provided
3 1 3 2 The high and low -voltage compartment shall be located side by side
on one side of the transformer tank When facing the compartment,
the low -voltage compartment shall be on the right.

368-300
REV. SYM. CC
3 1 3 3 Construction of the unit shall be such that it can be lifted,
skidded, and slid into place on the mounting pad without disturbing
the entrance cables
3 1 3 4 An undercoating over the regular finish or an equivalent treatment
shall be applied to all surfaces that are in contact with the pad to
minimize corrosion
3 1.3 5 Minimum dimensions shall be as shown in Fig 1 or Fig 2 of this
Specification Maximum transformer and minimum pad dimensions are
shown in Fig 6 of this Specification
3.1 4 LOSSES
The total losses of a transformer shall be the sum of the excitation
losses and the load losses (I'R losses) Load loss tests shall be
performed and reported on all units regardless of whether or not a
record of such tests is available on duplicate units Loss
evaluations and loss costs will be based on the values shown in the
"Special Conditions and Supplemental Instructions to Bidders."
Transformers will be evaluated on excitation losses and I'R losses
at the specified rates If tested losses exceed quoted losses but
are within the tolerances of Table 18, ANSI C57 12 00-1987, 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 In Table 18 and the following equation
"Units" shall mean "Transformers of the same size and desiq_n on one
order "
Excess loss $ _ [No of units] [(No Load Loss Evaluation $) (Avg No
Load Losses Quoted No Load Losses) + (Load Loss Evaluation $)
(Avg Load Losses - Quoted Load Losses)]. 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 18, ANSI
C57.12.00-1987, that unit or units shall not be shipped without
express permission from the City. 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 + (Load Loss Evaluation $) (Load
Losses - Quoted Losses) But Not Less Than Zero
3 1 5 SERVICE CONDITIONS
Service conditions shall be as defined in paragraph 4 1 of ANSI
C57 12 00 except the ambient temperature range shall be 400C above
to 32°C below zero The transformer shall operate safely with
starting temperatures as low as 32°C below zero
