To improve motor reliability and move to predictive maintenance for motors, tools are needed to assess the condition of the windings. There are several old and new test methods that have gained popularity with AC squirrel cage induction motor mainten

2015 IEEE 11th International Conference on the Properties and Applications of Dielectric Materials (ICPADM).
On-line partial discharge (PD) measurement is now widely applied to motors rated 6 kV and above that are fed from the 50/60 Hz power system. However, during the past several years, many motors are being powered from inverters which facilitate variabl

Proceedings of 2014 International Symposium on Electrical Insulating Materials.
In the past 10 years, motors rated 3.3 kV and above are increasingly being fed from voltage source, pulse width modulated converters to control motor speed and power output. Such converters produce short risetime voltage impulses that can accelerate

Diagnostic tests such as insulation resistance, polarization index, dissipation factor, capacitance and partial discharge can be useful to diagnose the condition of the stator winding insulation, and identify many problems that could lead to insulati

The authors describe an attempt to assess the condition of stator insulation in standby generators in two generating stations. The insulation condition was estimated by comparing diagnostic test results for different machines with similar insulator o

Modern inverter fed motors often produce short risetime, high magnitude voltage surges that may lead to partial discharge in the random wound stator windings. Detection of PD during such voltage surges can not be done with the usual PD detectors desc
