The invention provides a metering method for anti-stealing
electric energy meters, comprising the following steps: S1, the
electric energy meter starts to run; S2, judges whether the preset
electricity stealing condition is satisfied, that is, the
magnetic field strength of the
electric energy meter is greater than 150m'T; if satisfied , then enter S3; if not satisfied, return to S1; S3, whether the preset selection compensation mode is automatically activated, if activated, then enter S4; if not, then enter S6; S4, use the compensation measurement formula P=U*I max Calculate the pulse output, and
record the
voltage and current parameters, enter S5; S5, exit the compensation mode, use the normal measurement formula P=U*I to calculate the pulse output, enter S7; S6,
record the time to meet the preset
electricity stealing conditions segment
start time T 3 and end time T 4 ,
record T 3 ~T 4 Instantaneous maximum value of current within I max ,
voltage value U; S7, end. The present invention is provided with a compensation mode, which can automatically calculate the
power loss of the electric energy meter during the
electricity theft time period, or record various parameters of the electric energy meter during the electricity theft time period, so as to facilitate subsequent
recovery.
