Winding can fail over an extended period of time, and without proper testing equipment it is hard to determine the cause. Our equipment allows us to test winding of the most powerful motors on the market.

Hi-Voltage Motor's winding testing

4000 volt motor’s winding is being tested

With over $75,000+ invested in our winding analysis equipment, we catch:

  • Early phase to ground leakage
  • Phase to phase leakage
  • Resistance imbalance between phases
  • Inductance imbalance between phases
  • Impedance imbalance between phases
  • Phase angle imbalance between phases

An Example of such:
