General straight-through single-phase meters and three-phase meters can directly read the number, minus the last reading is the electricity at this stage. What about smart meter readings? The smart meter has only one LCD screen. If it is a single phase, it will directly display the total power and remaining power, and you can directly read it.

1. The general straight-through single-phase electric meter and three-phase electric meter can directly read the number, minus the last reading is the electricity at this stage.

2. How to see the degree of a three-phase electric meter, the three-phase electric meter is connected by a current transformer connection mode, the wiring of the electric meter has 10 wires, and the current ratio of the connected current transformer should be observed. The nameplate of the current transformer has , Are all marked with a number ratio of 5, such as 100/5 150/5, etc. The number read on the meter is multiplied by the current ratio to measure the amount of electricity, and the variable loss and line loss must be added accurately.

3. How to read the degree of single-phase electric meter, single-phase electric meter measures the electric quantity of three-phase electricity, the electric energy reading method is the way of connecting the electric meter directly, read the number on the electric meter multiplied by 3, if the electric meter connected through transformer To read the meter number multiplied by the transformer current multiple and then multiplied by 3.

4. How do smart meters see degrees? Smart meters have only one LCD screen. If it is a single phase, it will directly display the total power and remaining power, and you can read it directly. If it is an IC card electricity meter, only the luminous tube display is a single graphics card meter, then there will be a small red dot on the electricity meter. The small red dot jumps to the total use, which is the total use, and jumps to the rest, it is the surplus. Dual graphics card, you can read above or below. Direct reading of three-phase prepaid electricity meters with direct input. The reading of the mutual inductance meter is multiplied by the transformer ratio.
