Abstract

Procedure to monitor the operation of an electric receiver in the event of a short circuit, characterized in that the speed of variation of the voltage (eu) applied to the electric receiver is compared with a preset speed of variation and in the case of exceeding the preset speed of variation a monitoring, warning or disconnection signal is generated.
