摘要： A portable test device (1) can be configured as a rotor conductivity anomaly tester, a magnetic core anomaly tester, or a rotational eccentricity fault tester for a multiphasic motive force electrical machine (6) by providing an immotive multiphasic motive force electrical machine test signal from a plurality of multiphasic motive force electrical machine signal generators (4) through a detachable electrical power connectivity (2) and by having a multiphasic motive force electrical machine fault analyzer (16) that can sense responses and discern the existence of a fault. Control of the test signal can be accomplished by an immotive multiphasic test signal controller (3) that varies frequency and achieves incremental movement or to achieve stator magnetization plane angle changes or movement that tests angular relationships.

摘要： An easily implemented method of diagnosing both supply path, upstream, and load path, downstream, anomalies such as impedance events in machine or motor circuitry is accomplished by analyzing the across-the-line startup current and voltage time waveforms. No line of sight limitations exist and high accuracy exists. The techniques can be automated estimating poor contact resistance based on the voltage and current variation under a load change condition perhaps such as startup and/or shutdown of the load. Both, upstream and downstream problems from the point of voltage measurement can be monitored analyzing a load change condition. Additionally, downstream problems can be identified by using negative sequence current under steady state operation of the load.
