A) Schedule A: Switchgear and Switchgear Assemblies: 1) Visual and Mechanical Inspection: a. Inspect for physical, electrical, and mechanical condition. b. Inspect all doors, panels, and sections for paint, dents, scratches, fit, and missing hardware. c. Inspect all bus connections for high resistance. Use low-resistance ohmmeter, or check tightness of bolted bus joints by using a calibrated torque wrench. Refer to manufacturer's instructions or Table A-1 for proper torque levels. d. Clean entire switchgear, Insulators and standoffs using manufacturer's approved methods and materials. e. Inspect insulators for evidence of physical damage or contaminated surfaces. f. Verify proper barrier and shutter installation and operation. g. Lubrication: (1) Verify appropriate contact lubricant on moving current carrying parts. (2) Verify appropriate lubrication on moving and sliding surfaces. h. Exercise all active components. i. Inspect all mechanical indicating devices for proper operation. j. All power cable terminations to be checked for tightness and cleaned. k. All air passages and grillwork will be cleaned and cleared. The heaters will be checked. The operating face and window will be detergent cleaned. 2) Electrical Tests: a. Determine accuracy of all meters. b. Control Power Transformers - Dry - Type (1) Inspect for physical damage, cracked insulation, broken leads, and tightness of connections, defective wiring, and overall general condition. 3) Test Values: a. Bolt-torque levels shall be in accordance with Table A-1, unless otherwise specified by manufacturer. B) Schedule B: Air Switches, Medium Voltage, and Metal Enclosures 1) Visual and Mechanical Inspection: a. Inspect for physical and mechanical condition. b. Check for proper anchorage and required area clearances. c. Record fuse sizes and types. d. Perform mechanical operator tests in accordance with manufacturer's instructions. e. Check blade alignment and arc interrupter operation. f. Verify that expulsion-limiting devices are in place on all holders having expulsion-type elements. g. Check each fuse holder for adequate mechanical support for each fuse. h. Inspect all bus connections for tightness of bolted bus joints by using calibrated torque wrench. Refer to manufacturer's instructions or Table A1 for proper torque levels. i. Test all electrical and mechanical interlock system for proper operation and sequencing. j. Clean entire switch, insulator and standoffs using approved methods and materials. k. Verify proper phase barrier materials and installation. l. Lubricate per manufacturer recommendations. m. Check switch blade clearances with manufacturer's published data. n. Inspect all indicating devices for proper operation...
