The EN2079651-1 is an international standard set for digital energy meters for single-phase systems. It defines the requirements for accuracy, performance, environment and safety. These meters are commonly used in a wide variety of applications, ranging from home energy monitoring to high-precision industrial measurement. The specification is designed to ensure that digital energy meters are safe, accurate, and reliable for use in commercial and domestic applications.

Digital energy meters measure energy consumption by detecting and monitoring the electrical signals from both electrical grid and consumer equipment. They are designed to be accurate in measuring both active and reactive energy. They typically measure the electrical parameters of voltage, current, power factor, frequency, and phase displacement. The meters use these measurements to calculate the amount of energy used and then display the results in kilowatt-hours or other units.

Digital energy meters are designed to conform to the EN2079651-1 standard. This standard is based on the IEC 62052-11 standard which defines accuracy requirements and test procedures for energy meters. Digital energy meters must be designed and constructed in such a way that they are able to accurately measure energy usage over sustained periods of time. The EN2079651-1 requires meters to be tested and calibrated in an accredited laboratory for precise accuracy.

Digital energy meters have a wide variety of applications. In the home, they are used to measure the energy consumption of specific appliances and systems. This can help homeowners to reduce their energy use and save money. In the industrial setting, digital energy meters are used to measure the energy consumption of machinery and other processes. This can help companies identify areas where energy efficiency improvements can be made. Additionally, digital energy meters can be used in research, to monitor the performance of energy systems, and in other applications.

Digital energy meters work in a variety of ways. Depending on the type of energy meter, the signal may be measured using either direct or indirect measurements. Direct measurements are taken directly from the electrical equipment, while indirect measurements involve the use of transducers to convert the signal into a form that can be measured. The type of transducer used depends on the type of signal being measured. For example, transducers for measuring active energy use an induction coil. The output signal from this coil is then amplified, filtered, and rectified prior to measurement.

Digital energy meters also use a variety of display modes. The most common display configuration is a digital readout, usually displayed in kilowatt-hours or other energy units. Other display modes may also be available, including a graphical display showing current, voltage, and other parameters. Additionally, digital energy meters may be equipped with wireless capabilities, allowing them to be monitored and controlled remotely.

Digital energy meters offer a range of benefits over traditional analog meters. Unlike analog meters, digital meters are able to store and process data more accurately and efficiently. As such, they can provide users with more detailed energy consumption information. Additionally, many digital energy meters feature wireless capabilities and are capable of being monitored and controlled remotely. This is particularly useful for industrial applications, as it allows for automated energy monitoring. Digital energy meters are also becoming increasingly sophisticated, with many of the latest models offering advanced features such as real-time data monitoring, automated energy reporting, and energy alerts.
