Embodiment Construction
[0034] The technical solutions of the present invention will be further described in detail below with reference to the accompanying drawings.
[0035] For single-phase users, the A-phase current and neutral current should be the same. For the inconsistency between the A-phase current and the neutral current, it is defined as a single-phase meter shunt.
[0036] like figure 1 As shown, the present invention comprises the following steps:
[0037] 1) Call the A-phase current and neutral current of the low-voltage single-phase user smart meter once a month;
[0038] 2) Obtain the A-phase current and the neutral current, and determine if K1 < neutral current < K2, whether (neutral current-A phase current) / neutral current exceeds K3, if it exceeds K3, it is considered that the single-phase meter is shunted; which is:
[0039] K10
[0040] In the above formula: I 0 zero line current;
[0041] And, (I 0 -I A ) / I 0 >K3; K3 takes 50%;
