What do you think of ic card meters? Detailed explanation of four strokes

Ic card ammeter, that is, the intelligent ammeter we often see now, has the characteristics of multi-function and low bit error rate compared with the old ammeter. Now most cities in China have used this smart meter, but in real life, many people are not familiar with this ic meter, especially some middle-aged and elderly people. So how to teach them to look at their watches? Bian Xiao suggested that you might as well take a look at the following tutorial on ic electric meters, which introduces four ways to look at electric meters. Only by reading them carefully and mastering them can we be a more competent "electricity meter teacher"!

First of all, we can directly read the figures displayed in the direct-drive single-phase meter, but it should be noted that the displayed figures do not represent the electricity consumption at this stage, but the accumulated electricity consumption, so we need to subtract the last reading from the displayed figures, and the rest is how much electricity we used at this stage. Three-phase meters look at it the same way.

Secondly, considering that some three-phase meters are connected by current transformers, it is necessary to compare the current ratio of 10 wires on the three-phase meters, and the power consumption is the product of the number displayed on the meter and the current ratio. This method may be complicated to calculate, but it is also the only calculation method for those friends who connect meters with current transformers.

The third way to read an electric meter is to consider the electricity consumption of a single-phase electric meter. At this time, we have to multiply the reading of the single-phase meter by 3 to calculate the current of the three-phase meter. If it is an electric meter using a transformer, we have to multiply it by the current multiple of the transformer, so don't forget this step.

Now let's talk about the final reading method of the electric meter. First of all, we all know that most ic card meters have LCD screens. If it is a single-phase meter, the total power and remaining power will be displayed on this LCD screen, and we can read it directly. But if only LEDs have no display screen, we should pay attention to the readings of little red dot and little red dot on the electric meter where they jump. For example, when the words "remaining power" jump, now is the reading of remaining power.

Anyway, having said that, I believe that these reading methods of ic card meters should be enough for you to use in front of your computer in your life. Bian Xiao here suggests that you should always check the electricity meter. The first reason is to know the reading of the electric meter, and the second reason is to find and eliminate the reading failure of the electric meter in time.
