Went from dual sensing bay-o-net (expulsion) fuses to current sensing bay-o-net (expulsion) fuses. Fuse sizing was changed as follows: • Changed 25 kVA from 8A expulsion / 40 amp CL to 10A expulsion 130A CL • Changed 50 kVA from 15A expulsion / 80 amp CL to 15A expulsion / 40A CL • Changed 100 kVA from 25A expulsion 1175 amp CL to 25A expulsion / BOA CL • Changed 167 kVA from 40A expulsion / 200amp CL to 40A expulsion / 125A CL • Changed 250 kVA from 65A expulsion / 350amp CL to 65A expulsion / 125A CL 2 368-120 REV.

SYM: FF SPECIFICATION FOR PAD -MOUNTED COMPARTMENTAL -TYPE SINGLE-PHASE DISTRIBUTION TRANSFORMERS WITH SEPARABLE INSULATED LOAD BREAK HIGH -VOLTAGE CONNECTORS 1 SCOPE This Specification establishes the minimum electrical requirements and mechanical features of single phase, 60 HZ, mineral oil immersed, self -cooled, pad -mounted, compartmental -type distribution transformers rated 250 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 with ANSI requirements for pad -mounted compartmental -type, self -cooled, single- phase, distribution transformers, C57.12.25. 2 APPLICABLE DOCUMENTS The fallowing documents of the issue shown form a part of this Specification to the extent specified herein. In those cases when the document is note dated, the latest issue in effect on the date of invitation for bids shall form a part of this Specification. 2.1 ANSI C57.12.00 - Distribution, power, and regulating transformers, and shunt reactors, general requirements for. 2.2 ANSI C57.12.25 - Pad mounted, compartmental -type, single-phase, distribution transformers with separable H-V connectors, standard requirements for. 2.3 ANSI C57.12.28 - Switchgear and Transformers - Pad -Mounted Equipment -Enclosure Integrity. 2.4 ANSI C57.12.70 - Terminal markings and connections for distribution and power transformers. 2.5 ANSI C57.12.80 - Terminology for power and distribution transformers.

In case of conflict, the requirements of the following documents shall apply in the priority shown: a) This Specification b) Applicable ANSI Standards Approved manufacturers are listed in Appendix C. 4 368-120 REV. SYM: FF 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 80°C hot spot temperature rise. The temperature rise of the insulating oil 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. The transformers shall be designed for overloads based on IEEE C57.91. 3.1.3 GENERAL CONSTRUCTION 3.1.3.1 The pad -mounted compartmental -type transformers shall consist of the transformer tank and high -and -low - voltage cable terminating compartment constructed in accordance with ANSI C57.12.25 and ANSI C57.12.28. The terminating compartment and tank 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. The cover shall be welded construction. 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 side 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 for Type 1 transformers shall be as shown in Figure 1, Appendix B. Minimum dimensions for Type 2 transformers shall be as shown in Figure 2, Appendix B. 3.2 SPECIFIC DESIGN REQUIREMENTS 3.2.1 FUNCTIONAL DESCRIPTION The transformer shall be a single phase, pad mounted, loop feed -safe break, "dead -front" type for use on a 13.8 kV grounded "Y" distribution system. 3.2.2 DESIGN AND CONSTRUCTION 3.2.2.1 RATING The transformer shall be rated as follows: a) High Voltage 13,200 Grd. Y17620 volts b) Low Voltage 240/120 c) Taps Two - 2%.% FC above and below normal d) Polarity Additive e) Capacity, Impedance values, and fusing for transformers in this specification shall conform to Table 1: 5 368-120
