The test enables predictive maintenance on motor and turbine generator stator windings, resulting in increased availability and extension of operating life. The technique was introduced over two decades ago and has since been applied to over 6000 motors and turbine generators to identify deteriorated stator windings. It is by far the most popular method in the world for measuring motor and generator partial discharge (PD).
The method is non-destructive and based on sound scientific and empirical principles, and is recommended by manufacturers and industry standards such as the IEEE Std. 1434-2000.

Specifications
350 MHz bandwidth at the 3 dB cut-off frequency
850 MHz (clock speed) digital circuitry for separating noise (interference) pulses from PD pulses by directly recording the number and magnitude of the pulses
Input impedance of 50 Ω to avoid impedance mismatching
Input signal range of 2 mV to 3400 mV
16 windows/step pulse height analysis for each pulse polarity, in order to display PD magnitude vs. repetition rate
100 windows/step pulse phase analysis, in order to resolve where the partial discharges occur with respect to the power frequency phase angle to within 3.6º
User selectable data acquisition time between 1 s and 5 s for each coupler pair
