I'll teach you how to read an electric meter.
1. Ordinary straight-through single-phase and three-phase meters can directly read numbers, and finally the electricity consumption at this stage is read.
2. The three-phase ammeter is connected through a current transformer. There are 65,438+00 wires connected to the ammeter. It is necessary to observe the current ratio of the connected current transformer. On the nameplate of current transformer, the number ratio of 5 is marked, such as 100/5, 150/5. The number read on the ammeter multiplied by the current ratio is the measured electric quantity, and the accurate number should be added.
3. Smart meters have only one LCD screen. If it is single phase, the total power and residual power will be displayed directly, which can be read directly. If it is an IC card meter, and only the LED shows a single display card meter, then there will be a little red dot on the meter, and the red dot will be used all the time when jumping to General, and the rest of the time will be left. Double graphics card table, read above or below.
4. Identify numbers. Household electric meters should be inspected before leaving the factory, and a certain number should be drawn. The red letter after the decimal point is lower than 1 degree, the digit after the decimal point is 1 degree, 2 degrees is 0.2 degrees, and the black word before the decimal point is 1 degree, 1 degree, and 2 degrees is 2 degrees.
I sum up: what brand to buy and how to look at the household electricity meter are enough. I hope this knowledge can help you! Household appliances are a necessity for every family. Learning to look at the electricity meter is also helpful for us to use electricity at ordinary times, and it also helps us learn how to save electricity.
