Monitoring system for remotely monitoring a state of pole-mounted equipment in a power distribution or transmission grid, grid equipment having the monitoring system, and corresponding method

A monitoring method for remotely monitoring a state of a plurality of pieces of pole-mounted equipment in a power distribution or transmission grid, wherein the pieces of pole-mounted equipment each comprise an indicator device that generates indicator data including state information indicative of the state of the respective piece of pole-mounted equipment, wherein the indicator device comprises a fixed part and a moving part that is movable relative to the fixed part from a first static position indicative of a deactivated state to a second static position indicative of an activated state, wherein the monitoring method is carried out via a monitoring system comprising a status monitoring device movable via a drive or propulsion system, wherein the monitoring method comprises:

• moving the status monitoring device to a location within a communication range of the respective indicator device;
• and
• obtaining the indicator data from the indicator device, wherein the state information is indicated by the moving part of the indicator device being in one of the first static position relative to the fixed part or the second static position relative to the fixed part, and wherein the status monitoring device comprises an optical detection device for determining the state information based on optically detecting whether the moving part of the indicator device is in the first static position relative to the fixed part or the second static position relative to the fixed part.
