How to read an electric meter with a transformer

Let's look at the magnification of current transformer, for example, 75/5 is 15 times, and 100/5 is 20 times. Subtract last month's reading from this month's reading and multiply it by the multiplier, which is equal to the actual number of this month.

There are three sets of numbers in the electric meter, which are always equal to the peaks and valleys. The peak is daytime electricity consumption, and the trough is nighttime electricity consumption.

6078 kWh, if the inductor is connected, it needs to be multiplied by the inductance multiple. The electricity charge is the meter reading * unit price 6078* 1=6078 yuan.

Through the above methods, I believe you must know something about the reading of electric meters. If you really don't understand, you can ask the staff of the residential property or power company for help, and don't disassemble the meter yourself.

This kind of electric meter is a multifunctional rate meter, which displays 50-70 parameters circularly, and the top line shows the meaning of the current number.

The reading you need to see is the top line of Chinese characters "the total number of activities in the current month", please pay attention.
