Monitoring, Troubleshooting & Repairs of Electrical Apparatus & Other Electrical Systems (EASA)

At AAI, A Power-Flo Technologies Company, we offer complete monitoring, troubleshooting and repair of all types of industrial electrical equipment including controls, transformers, drives, electric motors, and other electrical systems. Capabilities include both field service and in-house repair or rebuilding of equipment and machinery. Field services such as vibration analysis, rebalancing, and specialized cleaning are designed to prevent costly repairs and corresponding downtime by properly maintaining equipment, minimizing the risk of failure. Our engineers can perform a site analysis to determine whether equipment is functioning efficiently and safely. If a fault does occur, we specialize in troubleshooting equipment using safe testing methods to determine the root cause of the issue. Winding faults are one issue that is routinely misdiagnosed by other electrical equipment service technicians. Typical testing methods are only able to recognize ground faults, which only represent approximately 5% of winding faults in electric motors. Most faults start out between windings in a coil, between the coils within a phase, or between coils in different phases. These faults are not detected through the standard Megohm Insulation testing method, but if left unchecked, will ultimately lead to a ground fault and motor failure. We are capable of testing unenergized motors to recognize these types of faults before failures occur, saving costs and preventing downtime.

Emergency response services are available during weekends or holidays and multiple repair shifts are run at our facility to expedite repairs without incurring overtime charges. For additional information about our extensive mechanical and electrical equipment repair capabilities or other engineering services, see the table below, or contact us directly.
