Method and device for detecting a shunt between the power input and output of an electricity consumption meter
The method involves generating a signal and modifying the signal by a conversion component at an electricity consumption meter (10) between a power input (12) and a power output (14) of the meter. Another signal is analyzed between the component and the power output. Presence or absence of a shunt (...

| Zusammenfassung: | The method involves generating a signal and modifying the signal by a conversion component at an electricity consumption meter (10) between a power input (12) and a power output (14) of the meter. Another signal is analyzed between the component and the power output. Presence or absence of a shunt (15) between the power input and the power output of the meter is deduced. Intensities of currents circulating in power conductors between the input and the output are determined, where individual values of current and/or a vectorial sum of the currents and/or a differential value are determined. Independent claims are also included for the following: (1) a method for locating fraud by derivation of an electricity consumption reading meter placed on an electricity distribution network (2) a device for detecting shunt between power input and power output of an electricity consumption meter. |
