H261--TRIENNIAL ELECTRICAL TESTING

STATEMENT OF WORK Triennial Switchgear and Battery Testing Certification Rocky Mountain Regional Veterans Affairs Medical Center (VAMC) SCOPE OF WORK - OBJECTIVE The Department of Veterans Affairs has a requirement for triennial testing, full maintenance, preventive maintenance, certification and repair services at the Rocky Mountain Regional VA Medical Center at 1700 N. Wheeling St. Aurora, CO 80045. These procedures include emergency and non-emergency electrical systems, vital to the essential function of this medical facility. The services to be performed on Government-Owned Paralleling Switch Gear (PSG), Automatic Throw Over (ATO) and uninterruptible power supply (UPS) units are detailed below. The intent of this document is to present the items, supporting documents, procedures and actions required. - STATEMENT OF WORK Items and systems to be included in the Triennial Switchgear and Battery Testing Certification electrical are listed in para v of the Request for Quote (RFQ). The following tests shall be performed on the above items. (See section 3.1 – ‘Code and Regulation Compliance’). - Generator Paralleling Switchgear and Control; PSG & ATO Visually inspect the switchgear for damage and any unsafe operational conditions. Verify enclosure is properly secured to wall or floor. Verify the equipment ground connection is terminated. Verify equipment interior is clear of debris and unit may be operated. Test all lights and fuses. Verify with site personnel that equipment may be cycled/ operated and occasional service interruptions are acceptable. Also verify with VA electricians and coordinate outages with end users. Measure and record bus voltage and frequency (at meters). Verify all meters are operational and properly displaying values. Test DC source inputs for proper values. Verify proper operations and values of any protection relays. Verify the Master Operator Interface Panel (OIP) is operational, and all settings and values are correct. Record values of all measurements taken, voltages, amperage and frequency. Note any field adjustments. Note any recommendations relative to repairs or upgrades. Six-month parts and labor limited warranty period on any repairs performed. Clean the unit Contractor to provide 16 hours of labor for ABB Service Tech to review Supervisory Control and Data Acquisition (SCADA) and verify system meets NFPA 110. Reviews system for its overall health which will also include: Alarm Parameters BAUD rate of communication Sequence of Operation (SOO) Timing Training for Staff -Automatic & Manual Transfer Switches (ATS/MTS) The following test shall be performed on Automatic Transfer Switches: Fire Pump ATS to be included as a part of this testing. Visual and Mechanical Inspection. Inspect physical and mechanical condition. Verify appropriate contact lubrication on moving and sliding surfaces. Verify tightness of all control connections. Verify tightness of all lug connections in equipment Verify positive mechanical interlocking between normal and alternate sources. Verify enclosure is properly secured to the wall or floor. Clean the Transfer Switch Test all lights and fuses. Equipment interior is clear of debris and unit may be safely transferred. Verify with site personnel that equipment may be cycled/ operated and occasional service interruptions are acceptable. Also verify with VA electricians and coordinate outages with end users. Verify with site personnel that the engine-generators and associated switchgear system are in the AUTOMATIC POSITION and may be started and operated under load. Verify the equipment ground connection is properly terminated. Perform a MX Controller calibration for S1 and S2 source voltages. Measure and record S1 voltage and frequency. Measure and record S2 voltage and frequency. Record values of all measurements taken, voltages, amperage, frequency and millivolt. Note any field adjustments. Record MX Controller transfer log details. Note any recommendations relative to repairs or upgrades. Perform a NO-LOAD TEST or LOAD TEST of the transfer switch through the controller. To verify that it is functioning properly after testing and cleaning. - Switchgear and Switchboard Assemblies. The switchgear cubicles and circuit breaker compartments shall be cleaned and inspected for evidence of damaged or defective devices. The compartment space heaters shall be inspected for proper operation. All circuit breaker compartment function positions (disconnected, test and connected) shall be checked for proper operation. The compartment panel door latches shall be checked for proper operation. The circuit breaker racking mechanism shall be cleaned, inspected and lubricated. All potential transformer and control power transformer compartments shall be cleaned and inspected. All PT and CPT fuse clips and fuse ferrules shall be inspected and cleaned. The test data obtained shall be included as part of the Engineering Report provided to the POC. - Medium Voltage Vacuum Circuit Breakers Each vacuum breaker shall be cleaned and inspected for physical damage. All lubricant points shall be performed according to manufacturer's specification. A mechanical test shall be performed according to manufacturer's specifications. The test data obtained shall be included as part of the Engineering Report. - Substation Transformers (Dry Type) The transformer panels shall be removed to inspect the transformer connections, core assembly, and core clamps for discrepancies. The transformer shall be cleaned, and the connections shall be checked for tightness. All bus-work within the transformer compartment shall be inspected for evidence of overheating or weakening of the insulation supports. The bus mounting bolts and splice connection bolts shall be checked for proper tightness wherever possible. The auxiliary devices, such as fans and indicators, shall be inspected for proper operati…
