Abstract

An apparatus and method for remotely monitoring the performance of an electrical appliance utilising the mains power supply cables of the electrical apparatus (4, 5, 6). A remote unit (3) is provided which communicates, using a signal at between 90 kHz and 145 kHz modulated on to the A.C. power supply cable of the electrical apparatus (4, 5, 6), with a local processing means (17) provided in the vicinity of the electrical apparatus (4, 5, 6). A memory means is provided to store information relating to the performance of the electrical apparatus (4, 5, 6). A robust communication protocol is provided to ensure that data is not lost. A control means is provided in the vicinity of the local processing means (17) so that the electrical apparatus (4, 5, 6) can be controlled via the remote unit (3). The system is primarily designed for monitoring items of street furniture (4, 5, 6).
