Added: Sep 24, 2016 1:58 pm PERFORMANCE WORK STATEMENTRefurbish Detroit Circuit Breaker XJ2PR 161T0121 General Description1.1 Background The Eaton type 150VCP-WG63 circuit breaker is the circuit breaker for generator 2 at Detroit Dam, Oregon. During maintenance in May, 2012 the wipe measurement for phases A and C was observed to be unsatisfactory per the factory operation and maintenance manual. The breaker was removed from service and is in need of repair.1.2 Scope This scope of work (SOW) covers repair, refurbishment and testing of an Eaton type VCP-W vacuum circuit breaker for the Willamette Valley Project Office. In addition, a closure test tool shall be supplied with the refurbished breaker. Satisfactory completion of this work requires that parts be furnished and installed per factory procedures to restore the breaker to original factory performance standards as verified by testing performed in accordance with the factory's operation and maintenance manual (I.B. 32-255-1G - Eaton "Instructions for Installation, Operation and Maintenance of Type VCP-W Vacuum Circuit Breakers"). The full set of requirements is described in detail in section 3.1.3 Technical Point of Contact:Name/title: Steve Tanner, Electrical EngineerMailing Address: Foster DamPO Box 807Foster, OR 97345Email: steven.a.tanner@usace.army.milOffice Phone: 541-367-5124, X 362 Applicable Documents2.1 ANSI/IEEE C37.04 - Standard Rating Structure for AC HV Circuit Breakers2.2 ANSI/IEEE C37.06 - Preferred Ratings for AC HV Circuit Breakers2.3 ANSI/IEEE C37.09 - Standard Test Procedure for AC HV Circuit Breakers2.4 I.B. 32-255-1G - Eaton "Instructions for Installation, Operation and Maintenance ofType VCP-W Vacuum Circuit Breakers".3 Requirements3.1 Repair and Reconditioning Services 3.1.1 Replace all tee vacuum pole assemblies with new assemblies of the same or superseding type meeting IEEE/ANSI C37.04 and C37.06 standards.3.1.2 Install X-Washers kit per figure 6-1b of I.B. 32-255-1G.3.1.3 Class 2 reconditioning service per Eaton services brochure3.2 Supplied Equipment3.2.1 Closure test tool, part #: (6352C58G01)3.3 Nameplate Information All parts and repairs must be compatible with the Eaton type VCP-WG63 circuit breaker.
