The Condition Of The Energy Electronic Energy Meter

Edit:Ningbo Baibu Smart Technology Co.,Ltd  Date:Jul 13, 2017

In the operation of the energy Electronic Energy Meter appears creep, should meet the two conditions. (1) the current Electronic Energy Meter current coil should be no current; (2) power Electronic Energy Meter aluminum plate should be continuous rotation in a whole circle or more.

At the same time to meet the above two conditions can be set as the tally of the energy Electronic Energy Meter. Voltage in the rated value of 80% to 110% of the range caused by the creep, according to the relevant provisions of the regulations, the energy Electronic Energy Meter is qualified, not as a creep, but for the user, due to the problem of withdrawal of electricity, obviously as a potential Move and not as normal.

In order to correctly judge, according to the above conditions to be analyzed:

First, the current Electronic Energy Meter current loop without current

First of all, the user does not use lighting, fans, televisions and other household appliances, does not mean that no current in the current loop of the energy Electronic Energy Meter. For the following reasons:

1, inside leakage

Indoor wiring due to disrepair, insulation damage and other reasons to make the circuit to earth leakage, leakage current in the closing by the electric current Electronic Energy Meter current coil may make the energy Electronic Energy Meter rotation, this situation does not meet the conditions (1), it should not be defined as potential move.

2, such as the Electronic Energy Meter in the back of the sub-Electronic Energy Meter, the winter mistakenly removed the fan blades, etc., although silent, light and other obvious electricity phenomenon, but in fact the power Electronic Energy Meter has been loaded, of course, can not be used as a creep.

Therefore, in order to determine whether the energy Electronic Energy Meter itself fault potential, you must disconnect the power Electronic Energy Meter load side of the main switch, the individual circumstances have to disconnect the upper end of the main switch phase line.

Second, the energy Electronic Energy Meter should not be continuous rotation

In determining the current Electronic Energy Meter current loop without current, and then according to whether the continuous rotation of the dial in order to determine whether the creep.

To determine the continuous rotation is observed in the window of the energy Electronic Energy Meter turntable mark more than twice. After confirming the creep, note the time t (minute) and the Electronic Energy Meter constant c (r / kW.h), according to the following formula:

Should pay back the amount of electricity: △ A = (24-T) × 60 × D / Ct

Where T daily electricity time, h;

D energy Electronic Energy Meter dive days.
