Motor & Circuit Analysis

Dynamic (online) monitoring combined with comprehensive static (offline) testing enhances motor condition awareness. Both dynamic and static testing are non-destructive methods. Online monitoring of power circuit, overall motor health, load and performance issues can be achieved with the computer-controlled portable Explorer II instrument. The offline testing of electrical insulation and circuitry is preformed with computer-controlled portable AWA instruments. Static testing includes: winding resistance balance, insulation resistance (IR/MegOhm), polarization index (PI), DC high potential (HiPot), and surge testing (exclusive to Baker Instruments). Surge testing is the only way to detect turn-to-turn, phase-to-phase, and coil-to-coil insulation problems. Dynamic testing includes, but not limited to: voltage level, voltage unbalance, voltage distortion, service factor, overcurrent, efficiency, rotor bar, operating point, torque ripple, load history, haystack, and operating condition test.

ATS will perform non-destructive online and offline testing from the motor control center to the motor. Anomalies will be documented and addressed in a detailed report.
