SENSOR-BASED REMOTE CONDITION MONITORING DEVICE AND METHOD FOR DISCONNECTOR DEVICES

A device, a method and a system for monitoring an electrical connection status of a disconnector device (). The disconnector device () being connectable to pole-mounted equipment in a power distribution or transmission grid (), thereby disconnecting the pole-mounted equipment. The connection status monitoring device () comprises a determining section () configured to determine whether the disconnector device () has been activated and to generate connection status indicator data, indicative of whether the disconnector device () has been activated. The determining section () further comprises a wireless communication section () which is adapted to connect to a wireless communication infrastructure () using a wireless communication protocol, and to transmit the connection status indicator data over the wireless communication infrastructure ().
