Low or medium switchgear monitoring system

A low or medium voltage switchgear monitoring system, comprising:

• at least one sensor;
• a processing unit;
• and
• an output unit,
• wherein the at least one sensor comprises a microphone,
• wherein the at least one sensor is configured to acquire sensor data within a compartment of a switchgear,
• wherein the sensor data comprises first sensor data, and wherein the first sensor data comprises a first acoustic recording,
• wherein the sensor data comprises second sensor data, wherein the second sensor data comprises a second acoustic recording, the second sensor data being acquired a set time after the first sensor data,
• wherein the at least one sensor is configured to provide the first sensor data and the second sensor data to the processing unit,
• wherein the processing unit is configured to determine status information for the compartment of the switchgear, the determination comprising a comparison of the second sensor data to the first sensor data, and wherein the status information indicates that a change event in the compartment of the switchgear has occurred based on a determination that a change between the first sensor data and the second sensor data is greater than a threshold, and
• wherein the output unit is configured to output the status information.
