SYM: MM 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 -mounted, compartmen tal-type distribution transformers rated 2500 kVA and smaller, high voltage 13,200 Grd Y/7620 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, pawer, and regulating transformer s, and shunt reactors, general requirements for • ANSI C57.12.26 - Pad mooted, compartrtmental-ly, pe, 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 WA and smaller, requirements for • ANSI C57.12.70 - Terminal markings and corrections for distribution and power transformers • ANSI C57.12.80-Teminology for power and distribution transformers • ANSI C57.12.80 - Distribution, power, and regulating transformers, and shunt reactors, test code for • ANSIREEE 386 - Separable insulated connectors for power distribution systems above 600V NEMA STANDARD TR1-Trarsfommers, 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 modification and additions given in the subsequent paragraphs. In case of conflict, the requirements of the following documents shall apply in the priority shown: This Specification. ANSI C57.12.26 Other applicable ANSI and NEMA Standards. 3.1.2 KILOVOLT -AMPERE TEMPERATURE RATINGS IGlovolt-ampere ratings are continuous and are based on rat exceeding either a 65°C average winding temperature or an WC hot spot temperature rise. The temperature rise of the insulating al shall not exceed 65°C 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 compartmenaR ype transformers shall consist of the transformer tank, high -voltage cable terminating compartment, and the law -voltage cable-terninatin 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 fastening devices, which are externally removable, except the main cover bolts may be exposed. VVlmere the main cover bolts are exposed, the 5 368-300 Opal Dick- 368dash300.pdf Page 6 REV. SYM: MM comer bolts shall be welded or otherwise render ed tamperproof. There shall be no opering 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 law -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 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 16 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 slipped 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 32"C below zero. The transformer shall operate safely with starting temperatures as law as 32"C below zero. 6 368-300
