37.221 application field and working principle

IEEE 37.221 has become the standard for residential electricity metering and power quality monitoring. It was officially approved at the meeting of several industry-leading companies from the IEC 62277 Standard Advisory Group (SAG) held in June 2020. The scope of this standard covers the functional requirements, safety, and electromagnetic compatibility (EMC) of residential electricity meters.

This standard addresses the issue of electric power supply quality by specifying requirements for residential electricity metering. It includes a measurement accuracy (MA) requirement for the measurement of active energy, reactive energy, and apparent energy, as well as an accuracy requirement for the connection and disconnection times of electric devices. It also sets limits on harmonic currents, harmonics of voltage, and power frequency values.

The working principle of IEEE 37.221 is based on three main parts. The first part is the metrological component, which is responsible for the accurate measurement of electric quantities. The second part is the safety component, which ensures the safety of people and equipment near electricity meters. The third part is the communication component, which enables communication between the electricity meter and the user\'s computer.

The metrological component of IEEE 37.221 is made up of electrical, electronic, and mechanical elements. It consists of current transformers, voltage measuring devices, and other metrological components. The current transformers measure the amount of electricity consumed, while the voltage measuring devices measure the peak voltage supplied. The metrological component is responsible for the accuracy of electricity measurement.

The safety component of IEEE 37.221 is responsible for preventing potential hazards near the electricity meter, such as electric shocks, fires, and other dangerous occurrences. It consists of fuses, trip components, and other electrical protective devices that are responsible for disconnecting electricity supply during a dangerous situation. The safety component also provides information about the status of the electric meter, such as when it is in danger of being overloaded.

The communication component of IEEE 37.221 helps in providing a reliable means of communication between the electricity meter and the user\'s computer. It consists of smart radios, dedicated software, and communication protocols that enable communication between multiple electricity meters and users at the same time. The communication component is responsible for the security of the data transfers between the meters and the computer.

IEEE 37.221 is a standard for residential electricity metering and power quality monitoring. This standard ensures the quality of power supply and safety of people and equipment near the electricity meters. It also provides a reliable means of communication between the electricity meters and the user\'s computer. By adhering to this standard, manufacturers, consumers, and other stakeholders will benefit from reliable energy consumption measurements and general operational improvement.
