Abstract

A low or medium voltage switchgear monitoring system includes: at least one sensor; a processing unit; and an output unit. The at least one sensor acquires sensor data within a compartment of a switchgear. The sensor data includes first sensor data. The sensor data includes second sensor data. The second sensor data is acquired a set time after the first sensor data. The at least one sensor provides the first sensor data and the second sensor data to the processing unit. The processing unit determines status information for a compartment of the switchgear based on a comparison of the second sensor data to the first sensor data. The output unit outputs the status information.
