| Abstract |
Partial discharges (PD) are widely known to occur in medium- and high-voltage applications.Recently, it has been observed that owing to the use of modern variable frequency converters, anenvironment that contributes to partial discharges is also found in low-voltage motors. Low-voltagemachines are vulnerable to partial discharges because their winding insulation is not designed towithstand the phenomenon. As the number of inverter-driven systems is growing, the PD become acritical reliability issue. Therefore, methods to measure the phenomenon are required for the purposesof product development and maintenance. In this paper, detection of partial discharges in randomwound low-voltage induction motors is studied by applying a radio-frequency-signal-basedmeasurement setup for online partial discharge measurements. |
