Abstract
A device for monitoring an interruption unit in an electrical energy supply network. In order to reduce the cost incurred by a network operator in detecting and localizing tripped interruption units, the device has a sensor interface for connecting a sensor unit that records a measured value specific to the interruption unit. An evaluation unit is connected to the sensor interface and configured to detect a current change in terms of the current flowing through the interruption unit on the basis of the measured value. A communication interface is connected to the evaluation unit. In the event of a detected current change, a status signal indicating a critical status of the interruption unit is transmittable to a communication unit. We also describe a method for monitoring an interruption device, and a distribution station with a device for monitoring an interruption device.
