  1. Recommended PdMs Prior To Shutdown • Visual Inspection • Vibration • Wear in bearings, gears, belts • Alignment of rotating components • Balance of machines and loads • Lubrication of bearings • Looseness - mounting and wear • Resonances – naturally occurring • Infrared • MCC electrical components and connections • Rotating machines, loads and mechanical connections • Transformers • Bearing Discharge • VSD motors

  2. Recommended PdMs Prior To Shutdown • Power & Current Signature Analysis (CSA) • Motors for SF overloading, rotors, mechanical issues & start up issues • VSDs and Soft Starts • Transformers • Generators • PF measurement • Ultrasound • MCC electrical components and connections • Air Leaks • Partial Discharge (≥ 4 kV only) • MCC electrical components and connections • Motors • Generators • Transformers • Oil Analysis • Transformers

  3. Recommended PdMs During Shutdown • Visual Inspection • Electric Circuit Analysis • Motors & motor auxiliary components • Feeder cables • Motor rotors if problem suspected • Generators • Capacitors • Insulation Assessment (IR, PI, Hipot, Impulse & PD) • MCC electrical components • Motors • Generators • Transformers • Cables

  4. Torq Reliability Services Delivery Methods 1. Train & mentor your staff 2. Data Analysis of data collected by your staff 3. Supplemental Field Services during shutdowns or extraordinary circumstances 4. Turn Key Field Services including data collection and analysis per schedule

  5. Torq Technical Expertise – 1 of 3 • Insulation Assessment • Insulation Resistance/Polarization Index • DC High Voltage • AC Line Frequency High Voltage • VLF High Voltage • High Voltage Impulse/Surge • Off-Line Partial Discharge with Hipot and Impulse • On-Line Partial Discharge • Tan δ/Power Factor • Current Signature Analysis • Rotor Diagnostics • Load Diagnostics – Fans, pumps, conveyors, etc • Start Up Problems – Drives, Soft-Starts, Switchgear, etc. • Mechanical Diagnostics – bearings, gearboxes, etc
