Anatomy of the energy meter ANTI-TAMPER function

Image
As a measurement product of electric energy, the Watt hour meter is the basis for the operation and settlement of power generation enterprises and  end  users,  and High Accuracy, fairness and fairness are essential. As a metering product in the design also need to prevent being vandalism,  tamper  and other illegal behavior; in Southeast Asia, Africa, South America to prevent  tamper  of electricity demand is higher. Today I would like to share with you about the energy meter for  anti-tamper  measures. Seal, When the electric energy meter production test and verification are qualified, there are special personnel to seal the meter cover. when the installation of the electric energy meter is completed, the installer will seal the terminal cover of the electric energy meter. Once properly sealed, it cannot be opened without authorization, and cannot be reused after destroying, generally each seal is marked with a number or anti-counterfeit mark for easy management. Forging or opening t

The meaning of the parameters measured by the energy meter.

Energy meter is an instrument used to measure electric energy. Also be called electricity meter, electric energy meter. Electricity meter is the basis for the operation and settlement of electric power enterprises, but also an important link in the security of the power grid, residential households, industrial and commercial industrial units, etc. have adopted the electric energy meter, which is related to the livelihood of the majority of electricity users fundamental interests.   Today I would like to introduce to you the meaning of the parameters measured by the energy meter. 1.  Voltage,the difference in potential between two points where a unit of positive charge passes under the action of a power source. 2.  Current, is a flow of electrical charge carriers, usually electrons or electron-deficient atoms. The common symbol for current is the uppercase letter I. The standard unit is the ampere, symbolized by A. 3.  Power, is the amount of energy transferred or converted per unit tim

The history of electronic electricity meter

- Nov 24, 2022- With the market demand for energy meter function, the development of science and technology, energy meter in continuous innovation. 1881 according to the principle of electrolysis made energy meter, this kind of energy meter weighs tens of kilograms, very heavy, and no precision guarantee, but at that time is still as a major invention of science and technology. 1888 induction type energy meter (mechanical energy meter) was born, induction type energy meter structure is simple, safe operation, high cost, easy to mass production. In the 1960s, all electronic energy meters were introduced, and with the development of electronic technology, electronic energy meters have occupied the market with their absolute advantages, and have been upgraded and iterated, and are now the world of electronic energy meters.   Ordinary electronic energy meter: only the function of electricity measurement, ordinary counter energy meter, ordinary LCD energy meter.   Multi-functional meter: Wi

STS prepaid meters can actually be designed like this

  STS (Standard   Transfer   Specification) is a standard transmission protocol for prepaid meters, which was established in South Africa in 1997 as the STS Association organization and standardized as IEC62055 by the International Standards Association in 2005, becoming the only public prepaid transmission standard in the world. Most of African countries adopt STS meters, and some countries in Southeast Asia also have applications.  Yongtailong , as a long-established company in energy meter export, has several series of STS split Power meter to meet the needs of different markets. This time  Yongtailong   also launched a miniaturized, intelligent   din   rail series STS   prepaid kWh meter, with greater innovation points in function, let me carry out the secret. 1.  Basic Parameters: ü  voltage 230V ü  current 100A ü  frequency 50/60Hz ü  accuracy level 1.0 2.  Communication Mode:  to adapt to different application environments. ü  HPLC ü  4G 3.  Anti- Tamper   Design: ü  Live  wire
