The general principle of the present invention：
（1）Under normal circumstances, the electric current I being metered on synchronization metering device0Should be with actually flowing through on the metering device
Electric current（The electric current I of user equipment consumption1And the electric current I of this equipment consumption2）It is equal, i.e. I0 = I1 +I2；
（2）If there is stealing or meter metering it is abnormal in the case of, then I occurs0＜ I1 +I2Phenomenon.
Using 1：Stealing meter is investigated
Fig. 2 is shown in this application installation, in use, first distinguishing at the both ends of the current sampling circuit of present device by crocodile clip
It is fixed on low-voltage metering mechanism property right separation（First usually after the output end of scanning zone intercarrier electric energy meter 1 or table
The upper pile crown point of incoming cables of individual air switch 2）On the zero line and live wire at place, the operating voltage and current sample of collecting device body 3
The load current I in loop1；Foreign current measurement module 4 is placed in after property right separation again（Usually scanning zone intercarrier
The lower pile crown outlet of first air switch 2 after electric energy meter）Live wire or zero line on, according to scene be actually needed increase expand
Open up module.
Start present device afterwards, input the table address of meter to be checked, read in real time after first carrier unit index meter
Take current values I in table0, while the line current I that central control unit measures foreign current measurement module2With metering units
The load current I of acquisition1It is weighted current values I in rear and table0It is compared, is contrasted three times respectively：1st, customer charge
With apparatus body（Non- bringing onto load unit）, 2, customer charge and apparatus body（One grade of load）, 3, customer charge and apparatus body
（Two grades of loads）, such as load testing is I three times0=I1+I2, then then think that the meter amount is normal；If there is I in any one shelves0
＜ I1+I2, then illustrate that the table has few quantity calculation, the central control unit sends alarm command, if being carried out in downshift
Review measurement still has above-mentioned phenomenon, then can determine that the metering device has stealing situation.
Using 2：Table family relation is verified
Fig. 3 is shown in this application installation, and the inlet wire that scanning zone intercarrier electric energy meter 5 is connected to by service wire 7 in user family is spaced apart
6, in use, the both ends of the current sampling circuit of present device body 8 are separately fixed at into user family by crocodile clip first
In inlet wire be spaced apart on 6 on the zero line and live wire of pile crown point of incoming cables, then foreign current measurement module 9 is fixed in user family
Inlet wire is spaced apart on the live wire or zero line of 6 times pile crown outlets, and increase external expansion module is actually needed according to scene.
Start present device afterwards, input the table address of meter to be checked, read in real time after first carrier unit index meter
Take current values I in table0, while the line current I that central control unit measures foreign current measurement module2With metering units
The load current I of acquisition1It is weighted current values I in rear and table0It is compared, is carried out in the period of change of a load
Contrast three times：1st, customer charge and apparatus body（Non- bringing onto load unit）, 2, customer charge and apparatus body（1 grade of load）, 3,
Customer charge and apparatus body（2 grades of loads）, if third gear load testing is I0=I1+I2, then then think that the user Biao-family is closed
It is errorless, if I occur in any one shelves0＞ I1+I2Or I0＜ I1+I2Then illustrate that the table-family relation has the possibility of corresponding mistake, then
Still there is I after secondary reproduction measurement result0＞ I1+I2Or I0＜ I1+I2It can determine that table-family relation is wrong.
