Project Title: Annual Switchgear Transformer Maintenance Service
Place of Performance: McAlester Ammunition Plant
Period of Performance: 12-month duration
1. Purpose
Inspection, maintenance, testing and servicing of switchgear transformers equipment in accordance with ANSI standards within a defined mileage radius of McAlester Ammunition Plant, McAlester Oklahoma.
2. Scope of Work
Service Requirements:
1. Equipment to be Serviced:
Description Quantity
Square D Med. Voltage VR, 1SKV Breakers 13 ABB OC Micro-51 IFT Relays 49 ABB 79M Relays 4
GE PQM II 6
GE Multilin PQM 2 S&C Series 2000 Substation Circuit Switchers 2 ABB S0MVA Oil Transformers 2
ABB LTC USERM 200/600 2
Basler BE1-4570 2 Basler BE1-851 2 Square D 12470V Gen. Breakers 2
2. Medium Voltage Vacuum Circuit Breaker:
o The circuit breaker will be cleaned and inspected for physical damage.
o The breaker will be operated slowly to observe the motion of the mechanism while manually cranking it from the open to the close position.
o Mechanical tests will be performed in accordance with the manufacturer's specifications.
o The breaker will be lubricated in accordance with the manufacturer's specifications.
o An AC high potential test will be performed on each vacuum interrupter in accordance with the manufacturer's instructions.
o Primary contact resistance tests of each phase will be performed using a low reading ohmmeter.
o After cleaning a phase-to-phase and phase-to-ground insulation resistance test will be performed in accordance with the manufacturer's specifications and ANSI standards.
3. Switchgear and Switchboard Assemblies:
o The switchgear cubicles and circuit breaker compartments will be inspected for evidence of damaged or defective devices.
o Compartment space heaters will be inspected for proper operation. If applicable.
o Protective interlocks will be checked for proper operation.
o All circuit breaker compartment function positions (disconnected, test and connected) will be checked for proper operation.
o The buses and bus joints will be inspected. Bolted pressure connections will be checked for proper torque (tightness) where possible using a 200 Amp DLRO.
o Ground bus connections and supports will be checked for proper tightness on de-energized circuits.
o Compartment panel door latches will be checked for proper operation.
o The circuit breaker elevating/racking mechanism will be cleaned, inspected, and lubricated.
o All potential transformers and control power transformer compartments will be cleaned and inspected. All PT and CPT fuse clips and fuse ferrules will be inspected and cleaned.
o All PT's CPT's and CT's will be verified per drawings.
o Insulation resistance of each primary bus section will be measured phase-to- phase and phase-to-ground in accordance with ANSI standards.
o The test data obtained will be included as part of the Engineering Appraisal Report.
4. Substation Transformers (Liquid Filled) PM:
o Visually inspect substation transformers for damaged insulators, potheads, damaged bushings or indications of overheating of cable connections.
o Inspect transformer pressure relief devices, tap changers, liquid level indicators and cooling tubes for discrepancies.
o Check for proper tightness of all external bolted electrical joints.
o Perform visual and mechanical tests per manufacturer's specifications.
o Visually check the equipment ground and record the number and size of ground bus and straps.
o Inspect primary bushings, secondary bushings, cooling tubes and tap changers for evidence of oil leaks.
o On LTC units operate through all positions manually to ensure smooth operation. Operate with control switch, testing operation of limit switches, dynamic braking, position indicator, counters, and automatic features. Adjust control to values listed on the owner's single-line diagram.
o Perform a turns ratio test in all tap combinations.
