Key Assets Monitored

  • Gearboxes & Drives: main gearboxes, yaw/pitch drives, conveyors.
  • Main & Auxiliary Bearings: turbine/generator bearings, pump bearings, cooling tower gearboxes.
  • Hydraulics & Lube Systems: pitch/yaw hydraulics, EHC, lift and mobile equipment, cranes.
  • Engines & Gensets: diesel/gas engines for standby and peakers.
  • Transformers & Switchgear (where applicable): insulating oils and condition indicators.
  • Fuel & Coolant Systems: diesel quality for standby fleets, coolant condition for rotating equipment.

Generation & Prime Movers

  • Gas/Steam Turbines – lube oil varnish precursors, oxidation, water ingress, bearing wear, and EHC hydraulic health
  • Diesel & Gas Gensets – oil analysis for fuel dilution, soot, glycol/coolant leaks, wear metals, and TBN/TAN balance
  • Wind Turbine Gearboxes & Drives – gear tooth/bearing wear, particle contamination (ISO 4406), water and additive health; yaw/pitch hydraulics fluid condition – centrifugal, screw, and gear pumps used in process fluid transfer

Rotating Power & Drive Systems

  • Gearboxes & Final Drives – gear mesh wear, bearing degradation, incorrect viscosity/grade, varnish risk
  • Main & Auxiliary Bearings – oil/grease analysis for early wear, contamination, and improper lubrication
  • Pumps & Fans – hydraulic/lube system cleanliness, water ingress, and additive depletion

Electrical & Substation Assets (where applicable)

  • Transformers & OLTCs – insulating oil moisture, acidity/IFT, dielectric strength, and DGA fault signatures (thermal/arcing)
  • Switchgear/Breakers – insulating media checks and contamination assessments as applicable

Auxiliary & Support Systems

  • Hydraulic Systems (EHC, pitch/yaw, lifting) – fluid monitoring for contamination, water, and additive health; demulsibility and filter effectiveness
  • Braking & Actuation – hydraulic fluid quality, water, and wear debris for reliability of safety‑critical systems
  • Cooling Systems – coolant chemistry (pH/inhibitors), corrosion control, and liner‑pitting prevention
  • Compressed Air – moisture and oil carryover checks for pneumatic reliability

Fuel, Storage & Environmental

  • Diesel Storage/Standby Fuel – water/particulates, microbial activity, stability; tie‑back to engine oil fuel dilution risks
  • DEF/AdBlue – concentration/contamination checks to protect SCR systems
  • Spill/Environmental Media – when needed, testing to support compliance investigations

Facilities & Mobile Equipment

  • Cranes, Hoists, Material Handling – hydraulic and gearbox oil analysis for safe lifting operations
  • Station/Depot Generators – oil and coolant monitoring for backup power readiness
  • Track/Plant Maintenance Equipment – engine, hydraulic, and drivetrain analysis for reliability in field operations
