Title: DEVICE AND METHOD FOR COMPENSATING FOR A SHAFT VOLTAGE AND BEARING CURRENTS BY MEANS OF A CAPACITIVE COUNTER COUPLING
Abstract:
The invention relates to a device and a method for compensating for a shaft voltage on a shaft. In the process, a compensation circuit is used to generate a compensation voltage which is coupled directly or indirectly to the shaft via a coupling element. The shaft voltage is detected directly or indirectly on the shaft via a tapping element.
