Deenergized Testing Instrument

MOTOR GENIEŽ Outperforms the Megohmmeter

The MOTOR GENIEŽ can see more than a megohmmeter, resistance tester, or RCL tester, making it the perfect tool for troubleshooting, startup, and quality control of low voltage AC induction motors.

Test Capabilities

The handheld MOTOR GENIEŽ is an excellent troubleshooting tool that tests low voltage AC induction motors, finds winding faults such as turn-to-turn, coil-to-coil, and grounded windings.

The MOTOR GENIEŽ measures impedance (Z), phase angle (Ⲫ), current/frequency response (I/F), and insulation-to-ground resistance (500V or 1000V and measure to 500 megohm).

Although the MOTOR GENIEŽ testing range is dependent upon the motor, it has successfully tested AC motors of hundreds of horsepower in size.

About Winding Faults

Winding defects can occur due to insulation age, contamination, power surges, thermal overload, damaged wire/materials, vibration and other causes. They begin as energy crossing an insulation fault (such as moisture or contamination), which isolates at least one turn. This generates additional stress and heat across the defect, which progresses until an arc is drawn and the winding fails.

There are four basic types of winding faults.

  • Between turns in a coil
  • Between coils in a phase
  • Between coils in different phases
  • Between a coil or phase and ground

Only about 5% of electrical faults begin as a fault to ground. The other three fault types may or may not propagate into a ground fault as the failure becomes advanced. The short term result of these faults is reduced efficiency and higher operating costs.

Symptoms include:

  • Higher operating temperatures
  • Possible nuisance tripping
  • Reduced motor life

As faults advance, power and torque may decrease. However, the longer-term result is always motor failure.

Megohm insulation testing will only detect faults to ground. The majority of faults will go undetected using this method alone.

Surge testing requires the application of high voltages and currents, which can be destructive and actually generate faults. This aspect combined with the size of surge testing equipment makes it inappropriate for troubleshooting and predictive maintenance testing.

In addition, resistance and inductance-only (RLC) test methods don’t provide enough information for reliable fault detection and troubleshooting.

The ALL-TEST PROŽ MOTOR GENIEŽ is your best, most economical choice for fault detection and troubleshooting.
