SCOPE REV. SYM: MM This Specification establishes the minimum electrical requirements and mechanical features of three phase, 60 HZ, mineral oil immersed, self -cooled, pad -mounted, compartmental -type distribution transformers rated 2500 kVA and smaller, high voltage 13,200 Grd Y/7620 volts, with separable 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 compartmental -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 transformers, and shunt reactors, general requirements for • ANSI C57.12.26 - Pad mounted, compartmental -type, self -cooled three phase, distribution transformers for use with separable insulated high voltage connectors, high voltage 34,500 Grd Y/19,920 volts and below, 2500 kVA and smaller, requirements for • ANSI C57.12.70 - Terminal markings and connections for distribution and power transformers • ANSI C57.12.80 - 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 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 368-300 REV. SYM: MM 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. 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 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 I2R 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 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 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 400C above to 320C below zero. The transformer shall operate safely with starting temperatures as low as 320C below zero. 368-300 REV.
