Abstract
A radio-controlled device for use in a power distribution circuit, typically for tariff-switching, load-shedding or off-peak load-switching purposes, includes a radio receiver having an aerial circuit which includes a ferrite annulus. The device is typically mounted in an electricity meter connected in the power distribution circuit, with the ferrite annulus surrounding one or more wires of the distribution circuit down-circuit of the meter. The wire or wires surrounded by the ferrite annulus, which typically extend all over the house or other building in which the meter and the device are installed, therefore serve as an aerial for the radio receiver in the device, thus alleviating the problems which can arise when the device is mounted in a location where radio reception is poor.
