For the watt-hour meters directly connected to the circuit and the watt-hour meters used with the indicated mutual inducers, the measured energy can be directly read from the watt-hour meter. If the dd282 single-phase watt-hour meter did not have a red reading box on the rightmost side, then the black reading box would be an entire number. However, there was a scale on the right side of the rightmost (that is, single digit)"counting wheel". This scale was the reading after the decimal point. If there was a red reading box, then the red reading box would display the decimals. If the output of the watt-hour meter did not have a current transformer, then the reading displayed on the meter was the actual power consumption measurement reading. If the meter had a current transformer, then the actual power consumption = the actual reading × the multiplying power. When the watt-hour meter is marked with the words "10× kWh" or "100× kWh", the meter reading should be multiplied by 10 or 100 times to obtain the measured energy value. When the ratio of the matching mutual sensor and the watt-hour meter were different, the reading of the watt-hour meter must be converted to represent the measured energy value.

The price was 28 yuan. In terms of installation, such as when it was used in a rental house, it was relatively simple to install. Some could be stuck on the track, and when connecting the wires, it could be either from the top or bottom. Moreover, one had to pay attention to the power-off operation. The upper end was connected to the incoming wire, and the lower end was connected to the outgoing wire. After the power was turned on, the meter would immediately start recording. It also had the function of accurate measurement and power-off memory. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
If the single-phase meter current is 10 amps, this 10 amps may be the nominal current. The rated current was used to calculate the base current value of the load. The smaller the rated current, the smaller the starting current of the electric meter, and the more sensitive the electric meter was. For example, if the starting current of the meter is 0.5% of the nominal current, then the meter will start counting as long as the current in the meter circuit is higher than 0.05A, and the meter will not count if it is lower than this value. Single-phase electric meters often have different specifications such as 10, 20, 40, 60, 80, 100A, etc. When using an electric meter with 10A current, you need to consider its matching with the power consumption. The current parameters are neither the bigger the better nor the smaller the better. It should correspond to the power consumption. The maximum current of all electrical appliances should be calculated. If the current parameters of the electric energy meter are small, the electric energy meter may burn. Therefore, it is usually recommended to choose an electric energy meter with a slightly larger current parameters. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The single-phase watt-hour meter is mainly used for civilian use to measure single-phase AC active energy with a rated frequency of 50HZ or 60HZ. Its main structure was composed of a voltage coil, a current coil, a rotating disc, a rotating shaft, a brake magnet, a gear, a meter, etc. It was generally connected to 220V equipment.

A single-phase digital voltage meter was an instrument that measured the voltage parameters of three-phase electricity. The unit of measurement was volts (V). There are many types of common single-phase digital voltage meters, such as XC-db140S76- U single-phase digital display voltage meter. It can be used with mutual inducers, voltage diverters, etc. It can display the voltage, current and other parameters in the power grid. It has the advantages of high accuracy, strong isolation, stable performance, and easy installation. It uses a large screen liquid crystal display, which can display voltage and current values and other power parameters at the same time. The user can easily switch the display content by pressing the button, and can also send out an alarm for abnormal situations. The instrument has a variety of communication protocol, and can be connected with computers, Plcs and other equipment to achieve remote monitoring and data acquisition.

There may be several reasons for the single-phase electric meter to lose power: 1. Electricity meter internal fault: - It was possible that the voltage coil inside the electricity meter had burned out, causing the live wire to be out of power. - This could also be caused by the loosening of the No. 2 connection screw or the broken circuit of the No. 1 or No. 2 connection. 2. Connection problem: - If the live line and the neutral line were connected in the opposite direction, there might be a situation where the live line would be out of power and the neutral line would be out of power. However, according to the regulations, this was not allowed, but it had no effect on the operation measurement. 3. External circuit problem: - If there was a theft of electricity, such as replacing the chip resistance on the internal circuit board of the meter (the higher the resistance, the slower it would go, but it required welding technology), it might cause an abnormal situation where the live wire of the meter was out of power. However, stealing electricity was illegal. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
