The electr on ic energy meter is a metering device for measuring the consumption of electrical energy, which is the basis for collecting power operating expenses. What we often see in daily life is that  single-phase measuring devices  are mainly used for home users .  In addition,   Three -phase measuring devices  are mainly used for industrial users. The power supply voltage used in many countries around the world is different, such as  1 phase  2 wire,  1 phase  3 wire,  2 phase  3 wire,  3 phase  3 wire,  3 phase  4 wire, phase voltage of 110V, 220V . In South America,  2 phase  3 wire power supply is more popular, which requires a   two phase electricity meter   to measure power consumption. There are relatively few countries where   two phase kWh meter   is  used, and Colombia in South America has a  2 phase  3 wire power supply method, that is, two live wires an...

  The electr on ic energy meter is mainly composed of electronic devices, which use the voltage and current supplied by the user to sample in real time, and use a special metering integrated circuit to calculate and process the collected voltage and current to obtain the power consumption data. The current sampling devices commonly used in electr on ic energy meters are shunts, transformers, Rogowski coils, Hall sensors .  Shunt  energy meter  refers to an energy meter that uses a  Shunt  for current sampling. Shunts are generally used to extend the current range with a fixed low resistance. Simply put, the  Shunt  is actually a resistor with a small resistance, and a special manganese copper sheet is used as a resistance material, and when a current is passed, a voltage drop will be generated for the metering chip to collect data. As the core component of high-quality shunts, manganese copper has good electrical conductivity and magnetic permeabi...

  IEC is an international standardization organization dedicated to the development of international standards, including in power systems and electronic equipment.  IEC energy meter  standard is a standard developed and issued by the International Electrotechnical Commission (IEC) to establish a unified standard for electrical, electronic and related technologies worldwide. The energy meter standards of many countries are modified and formulated on the basis of IEC standards according to the special requirements of their own countries, and some countries will adopt IEC standards as the basis of their national standards, or refer to IEC standards in their national standards. In Europe, standards for energy meters are developed by the European Organization for Standardization (CENELEC), which is usually based on IEC standards. In the United States, standards for energy meters are developed by the American National Standards Institute (ANSI), and   ANSI electricity met...
