Abstract

This invention relater to a field excitation equipment for an electric machine, comprising an exciter which is connected to the field winding of the machine and an electric swith for breaking the field current. A discharge resistor is arranged to be connected to the field winding when the electric switch is opened. The equipment is characterized in that the discharge resistor is, in series with a controlled semiconductor element, connected in parallel with the field winding, and that a contact member is arranged, when the electric switch is opened, to connect the control electrode of the semiconductor element and one of the main current connections of the element in order to make the semiconductor element conducting.
