Abstract
The invention relates to a method and apparatus for identification of the disconnection of a protection device, in particular of a protection device which is connected in series with a semiconductor component and is arranged on a rotating shaft. According to the invention, electromagnetic pulses which are produced during disconnection of the protection device are received by an antenna which is arranged in the vicinity of the protection device.
Claims16
A method of identifying a disconnection of a protection device, which comprises:
- placing a protection device on a rotatable shaft and connecting the protection device in series with a semiconductor component;
- receiving electromagnetic pulses emitted from the protection device and from any other components which may be present and checking for electromagnetic pulses produced during disconnection of the protection device;
- and
- detecting a rotation position of the shaft via an encoder and linking the rotation position to the received electromagnetic pulses.
