Cost control and prevention of electricity theft in metering cabinets

Cost control and electricity theft prevention metering cabinet can prevent electricity theft by standardizing the installation and erection of low-voltage lines, mainly to prevent electricity theft without meter method, as well as wiring shunt in front of the electricity meter. The specific approach is:

1. The low-voltage mainlines and branch lines from the common transformer outlet line to the power side of the entry table should be arranged in the center to minimize detour and avoid crossing;

2. When the cable is used, the part near the ground should be laid through the pipe; When using overhead wire, should be clear and try to avoid wall installation;

3. The main line and branch line in front of the table should be clearly spaced from the rear entry line of the table, so as to avoid erection and crossing with the same pole as far as possible;

4. Phase and fire wires should be arranged in a certain order with wires of different colors;

5, different public transformer power supply users should be clearly separated from the street, the same building users should be supplied by the same public power supply, different public transformer platform area users do not help each other staggered.

When the metering cabinet USES electricity across phase between single-phase watt-hour meters of different phases, it may cause misalignment of measurement, and the measurement results of bidirectional metering or inverse meter cannot reflect the real electric quantity.
