Power plants operated with coal, natural gas or oil are the primary sources of power supply and therefore must be constantly available. Failure of a primary component not only has direct consequences locally, but can also affect the stability of the entire mains infrastructure.
Critical equipment monitored in power plants are:

• Vibration Analysis covers the widest spectrum of measurable faults in any rotating asset regardless of its driver (steam, hydro, gas, electric, internal combustion). Vibration is the most cost-effective method of providing a total overview of a facility’s health.
• Oil Testing benefits include the ability to detect wear particles from early bearing / gear wear far in advance of vibration detecting degradation. Oil analysis only provides information of wear particle detection, and cannot provide information the wide array of mechanical fault detections that can be learned with regularly scheduled vibration collections.
• Motor Testing much like oil analysis is pinpoint-specific to its role, however, motor testing done at periodic intervals can detect issues that no other PdM technology can. Motor testing can determine particular electrical faults early on that can be dealt with at relatively low-cost and with minimal downtime versus a core loss instance on a motor, costing hundreds of thousands of dollars in repair costs not to mention the losses attributable to downtime. Infrared can detect loose wiring connections, connector integrity trouble, and excessive current or heat dissipation due to overloading. Infrared is extremely beneficial in shooting yards, MCC buckets and connection heads on motors.
This allows the timely and cost-effective execution of corrective actions, such as shaft alignment or balancing.
