ABSTRACT:
An electricity metering equipment wherein, in order to reduce the possibility of fraudulent consumption of electricity, there is provided in addition to the usual meter (3) for measuring the amount of electricity consumed in a load, an independent device (5) which produces a signal representative of the current supplied to the load. A comparison device (4) then compares the signal with the rate of electricity consumption measured by the meter, and an output signal is produced if there is a discrepancy which may be used to disconnect the supply and/or transmit a signal to the supply authority.
