Abstract
A device for monitoring a supply line of a frequency converter-fed electrical machine is used to predict failure, wear and/or ageing of the electrical supply line. The electrical supply line is designed and installed to connect an electrical machine in an industrial machine or plant or in a land or aircraft vehicle to a frequency converter. The frequency converter is designed and intended to supply the electrical machine with a single-phase or multi-phase alternating voltage with preferably variable voltage amplitude and pulse duration through the electrical supply line, wherein a change in pulse duration and/or voltage amplitude of the alternating voltage serves to change a speed or torque of the electrical machine. The frequency converter is set up and intended to provide each phase of the AC voltage as a sequence of square-wave pulses with a high edge steepness for feeding the electrical machine.
