Manager Originated: January 10, 2002 Revised: February 21, 2002 368-700 1 of REVISION DESCRIPTIONS REVISION DESCRIPTION (Previous Revision Descriptions on File) CHANGE NOTICE APPROVED NEW 1/10/2002 Kraig Bader Tim M. Sagen REVISION A: 2/21/2002 Kraig Bader • Paragraph 4.a.8 added to include Pressure / Temperature gauge in Tim M. Sagen control compartment. 368-700 2 of 1. Scope This specification establishes the minimum requirements for single-phase, 60-hertz, thirty-two (32) step, padmounted voltage regulators providing a 10% regulation range. Applicable ANSI/IEEE, IEC and NEMA standards requirements shall apply except where specifically altered by this Specification. 2. Electrical Requirements a. Frequency: 60 Hertz b. Voltage rating: 7620 a. kVA: 416.3 kVA b. BIL: 95 kV c. Current rating: 546 Amps 3. Construction a. The regulator shall be rated for an average winding rise of 650C over a 300C ambient, and shall be capable of a short circuit of twenty five times rated current for 15 cycles. The regulator shall be provided with a 3kV under -oil, metal oxide varistor (MOV) bypass arrester connected across the series (low voltage) winding. b. Regulator 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 that are externally removable. 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. The cabinet shall be painted Munsell Green (7GY3.29/1.5). c. The cabinet shall be divided into two compartments defined as follows: 1) Operating Compartment: The compartment containing the high voltage cable connections and grounding equipment. 2) Control Compartment: The compartment containing the controller, and other status - indicating equipment. d. The operating compartment shall be separate from the control compartment, constructed with a full metal barrier separating the two compartments and shall contain: 1) 600A rated terminations 2) Two parking stands 3) Pads for grounding the equipment 4) Automatic pressure relief device 4. Regulator Controller a. Housed in the control compartment shall be a microprocessor -based control capable of: 1) Communications using Cooper Power Systems DATA 2179 protocol. 2) Operation between - 40°C and +85°C. 3) Digital metering of Class 1 accuracy with instantaneous and time and date stamped demand values. 4) Tracking Tap position. 5) Reverse power flow operation, including the ability to calculate the source voltage based on tap position and regulatortype. 6) Voltage -limiting operation. 7) Voltage -reduction operation. 8) Tank pressure / temperature indication shall be provided within the control compartment. 5. Testing a. The regulator shall be tested in accordance with the testing code in IEEE C57.15-1999, 'IEEE Standard Requirements, Terminology, and Test Code for Step -Voltage Regulators." Certified test reports shall be furnished with each unit. 368-700 3 of 6. Stock number coding Example: ME:* 368 - FERC Transformer Class 7+= Single Phase 8 = Three Phase OQ= 7620V Rated Voltage The stock number for the regulator described in this specification is: 700-3200 Other kVA 00 = 2250 1 = 333 2 = 416 Current Rating 1 = 328 2=438 3 = 54G Shipping a. Units shall be prefilled with the appropriate amount of non -PCB insulating oil and shall be shipped by open -bed truck. Units shall be packaged in such a way as to provide for ease of handling and to protect units from shipping damage. Units shall be packaged on four-way universal pallets with minimum opening not less than 34 inches and loaded on the truck for side removal. The Supplier shall give 24-hour notice prior to delivery for any shipments where an individual unit weighs over 5,000 pounds. In addition to these requirements, the Supplier shall comply with any additional requirements or modifications shown on the purchase order and/or supplemental instructions. 368-700 4 of 4
