the "Invitation to Bid" and the "Purchase Requisition".
1. Impedance volts in percent (%) at full load, high voltage to low voltage at 85°C
2. No load and total losses at 85°C
3. Delivery in weeks
4. A statement indicating compliance with our Specification with exception or a detailed list of exceptions.
5. Escalation IS / IS NOT applicable for the transformers bid. If escalation applies, the Bidder
shall indicate in his bid, the specific items or materials subject to escalation and shall provide the method
and indices to be used in computing the amount thereof. Escalation occurring after acceptance, if Purchaser
exercises the option to delay shipment after manufacturing is completed, will not be paid.
If the above information and compliance statement are not supplied the proposal will not be evaluated
An alternate bid for the total order may be submitted in addition to the unit bids.
B. Loss Evaluations
Loss penalties and loss evaluations will be based on the following values:
1. No-load or excitation losses at $3.90/watt
2. Load losses at $2.30/watt
C. Shipping Terms
Ship F.O.B. point of destination, freight prepaid.
D. Terms of Payment
1. If escalation applies, the City of Fort Collins shall not be billed for escalation occurring after the promised
delivery date.
2. Test reports shall accompany the invoice. If test reports do no accompany the invoice, late payment penalty
charges incurred due to delays in obtaining the test reports will not be paid. Certified copies of test reports
shall be sent to the Standards Engineering Section, Fort Collins Utilities - Light & Power.
3. Loss penalty credits and escalation charges shall be itemized on the invoice.

SPECIFICATION FOR
PAD -MOUNTED COMPARTMEN TAL-TY PE, THREE-PHASE
DISTRIBUTION TRANSFORMERS WITH
SEPARABLE INSULATED LOAD BREAK HIGH -VOLTAGE CONNECTORS
1. SCOPE
This Specification establishes the minimum electrical requirements and mechanical features of three phase, 60 HZ,
mineral oil immersed, self -cooled, pad-mormted, compartmen tal4ype distribution transformers rated 2500 WA and
smaller, high voltage 13,200 Grd W7620 volts, with separab le insulated load break high voltage connectors. These
transformers are used for step down purposes from an underground primary cable supply.
This standard generally conforms to ANSI requirements for pad -mounted compartm ental-type, self -cooled, three-phase,
distribution transformers for use with separable insulated high -voltage connectors, C57.12.26.
2. APPLICABLE DOCUMENTS
The following documents form a part of this Specification to the extent specified herein. The latest issue in effect on the
date of invitation for bids shall form a part of this Specification, unless otherwise noted.
• ANSI C57.12.00 - Distribution, power, and regulating transformer s, and shunt reactors, general requirements for
• ANSI C57.12.26 - Pad mounted, compartmental4y pe, self -coded three phase, distribution transformers for use with
separable insulated high voltage connectors, high voltage 34,500 Grd Y/19,920 volts and below,
2500 WA and smaller, requirements for
• ANSI C57A2.70 -Terminal markings and connections for distribution and power transformers
• ANSI C57A2.80 -Terminology for power and distribution transformers
• ANSI C57.12.90 -Distribution, power, and regulating transformers, and shunt reactors, test code for
• ANSI/IEEE 386 -Separable insulated connectors for power distribution systems above 600V
• NEMA STANDARD TR1 -Transformers, regulators and reactors
3. 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
lQovolt-ampere ratings are continuous and are based on riot exceeding either a 650C average winding
temperature or an 80°C hot spot temperature rise. The temperature rise of the insulating ell 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-t ype transformers shall consist of the transformer tank, high -voltage
cable terminating compartment, and the law -voltage cable-terminalin g 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 festering devices, which are externally
removable, except the main cover bolts may be exposed. Where the main cover bolts are exposed, the
5
368-300
Opal Dick - 368dash300.pdf Page 6�
REV. SYM: MM
comer bolts shall be welled or otherwise render ed tamperproof. There shall be no opening through
which foreign objects such as sticks, rods, or wire s 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.
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 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 (12R losses).
Load loss tests shall be perforned 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 RR losses at the specified rates. If tested losses exceed quoted losses but are within the
tolerances of paragraph 9.3, ANSI C57.12.00-2000, 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 design on one order."
Excess loss $ = [No. of units] [(No Load Loss Evaluat ion $) (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 arty unit or units exceed the tolerances of paragraph 9.3, ANSI C57.12.00-2000, 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 40'C above to 320C below zero. The transformer shall operate safely with starting
temperatures as low as 32°C below zero.
