There are four ways to see how smart meters look.
The first type: the general straight-in single-phase meter and three-phase meter can directly read the number minus the last reading is the power of this stage. The straight-through meter has a thicker incoming line and is carefully observed without a transformer connection.
The second type: the three-phase electric meter is connected to the three-phase electric meter through the current transformer connection. The wiring of the electric meter has 10 wirings. To observe the current ratio of the connected current transformer, there is a number on the nameplate of the current transformer. Than 5 marked. For example, 100/5150/5, etc., the number read on the meter multiplied by the current ratio is the measured amount of electricity, plus the variable loss and line loss.
Third: How do you look at the meter? The single-phase electric meter measures the electric quantity of the three-phase electric power. The electric quantity reading mode is a direct-connected way to connect the electric meter. The number on the electric meter is multiplied by 3. If the electric meter connected by the transformer is to read the electric meter number, multiply the current of the transformer. Multiply the multiple by 3.
The fourth type: The smart meter has only one LCD screen. If it is a single phase, it will directly display the total power and remaining power. Direct reading can be used. If it is an IC card meter, only the LED display is a single card table. There will be a small red dot on the meter. The red dot jumps to the total use there is the total use. Jumping to the rest is the remainder. Double graphics card, read above or below. The direct reading of the three-phase prepaid meter is straight-in, and the reading of the mutual-sensitivity meter is multiplied by the transformer multiplier.
