Method and apparatus for monitoring of shafts currents and shaft voltages in a generator.

摘要

The invention relates to a method for monitoring shaft currents (1) and shaft voltages (U) in the shaft (2) of a generator (4). The cause of the shaft current (1) or the shaft voltage (U) is determined using the frequency (F) of said shaft current (1) or the shaft voltage (U). The invention also relates to a corresponding device.
