EN 62053-23 is a European Standard that specifies requirements for static meters for active electrical energy (watt-hour meters) in direct current (DC) systems. This standard applies to meters used to measure the consumption of electrical energy in DC circuits, ensuring accuracy and reliability in various applications where DC energy measurement is required. EN 62053-23 ensures that static watt-hour meters for DC systems meet stringent standards for accuracy and reliability, supporting applications such as renewable energy systems, telecommunications, transportation (e.g., electric vehicles), and industrial processes where DC energy measurement is critical for operational efficiency and billing purposes.
