The three phase electricity meter multi-function intelligent electric energy meter uses the LCD screen to display the value of the electric energy, with a total of eight significant digits, of which two significant digits after the decimal point. It stands to reason that within a certain period of time, the increment of the total electric energy measured should be equal to the sum of the...

The three phase electricity meter active energy meter is a product manufactured using advanced microelectronic technology and SMT production technology. It is used for the measurement of three-phase AC active energy with a rated frequency of 50Hz. The three-phase active electric energy meter has infrared and RS485 port communication functions, adopts LCD display mode, and can be set and...

prepaid electricity meter    allow you to effectively manage energy usage and avoid adding debt to energy usage. As the name suggests, prepaid meters require you to pay for energy in advance. Prepaid energy meters allow you to control energy consumption, making it possible to check the remaining balance and recharge if necessary. With the advent of prepaid meters, it is easy to...

Due to the difference in equipment and power usage, the loss rate during the use of electrical energy is not very low, but it is not easy to avoid, and the electrical energy consumption of low-voltage power distribution terminals is large. In order to strengthen the measurement, evaluation and management of terminal energy, and to facilitate the use and transformation of users, a miniature...

When the electric energy meter is connected to the circuit under test, alternating current flows through the current coil and the voltage coil, and these two alternating currents respectively generate alternating magnetic flux in their iron cores; the alternating magnetic flux penetrates Passing the aluminum plate, the eddy current is induced in the aluminum plate; the eddy current is subjected...

Electricity meters are used to measure the amount of electricity or electricity consumed in factories and houses. The meter actually measures the electrical energy passing through the circuit. For direct current, the energy is A = V.I.t. In AC power systems, only watt-hour meters are used.Earlier electric meters (such as watt-hour meters) used to be used only for alternating current and are now...

1. Observe the dial pulse indicator flashing. Turn off the home meter box switch or unplug all the electrical equipment in the house. If there is no equipment in the power, observe the dial pulse light of the instrument flashing. Generally, it does not blink or flash once in 10 minutes. The instrument runs. If the indicator flashes, the meter is not operating normally. 2. The total number...

1. Whether there is a multiple depends on whether a mutual inductor is connected. 2. The multiple is the transformation ratio of the transformer. 3. The general current measurement range of the energy meter connected to zhi transformer is 5 (6) A. The energy meter you said is generally used for direct measurement without multiplication. [3*3(6)A] This kind of electric meter is generally used...

The actual inspection of the electric energy meter sent by the manufacturer is mainly carried out from the following aspects.Namely: five aspects: mechanical requirements, climatic conditions that can be adapted, electrical requirements, electromagnetic compatibility, and accuracy requirements. These five aspects are clearly defined in the national standard "Class 1 and Class 2 Static AC...
