IEC 62053-21 Electrical Measuring Equipment - Special Requirements - Part 21: Static Meters for AC Active Energy (Class 0,5, 1 and 2)

IEC 62053-21 Electrical Measuring Equipment - Special Requirements - Part 21: Static Meters for AC Active Energy (Class 0,5, 1 and 2)

In the IEC 62053-21 standard published by the International Electrotechnical Commission (IEC), the test methods applied to static meters in accuracy classes 50, 60 and 0,5 and only their type tests are described for the measurement of alternating current electrical active energy in 1 Hz or 2 Hz networks.

IEC 62053-21 Electrical Measuring Equipment - Special Requirements - Part 21: Static Meters for AC Active Energy (Class 0,5, 1 and 2)

This standard applies to the following types of electrical measuring equipment:

  • Designed to measure and control electrical energy in electrical networks up to 1000 Volt alternating current.
  • Designed to have all functional elements, excluding display screens, including additional modules built into it or forming a single meter casing.
  • Designed to work with or without integrated or split display screens
  • Designed to be installed in a specific matching outlet or rack
  • Optionally designed to provide additional functions other than those for measuring electrical energy.

However, electrical measuring equipment not covered by this standard is:

  • Meters where the line-neutral voltage obtained from the rated voltages exceeds 1000 Volts alternating current
  • Meters intended for connection with low-power instrument transformers when tested without such transformers
  • Measurement systems consisting of more than one device physically distant from each other
  • Portable counters
  • Counters used in wagons, vehicles, ships and aircraft
  • Laboratory and meter testing equipment
  • Reference standard counters
  • Compatible sockets or racks used for the installation of electrical measuring equipment

On the other hand, this standard provides a measure to detect and prevent fraudulent attempts to compromise the performance of a meter.does not cover the

In practice, the IEC 62053-21 standard is used together with the relevant parts of the IEC 62052, IEC 62058 and IEC 62059 standard series and the IEC 62055 standard series.

Among the numerous test, measurement, analysis and evaluation studies it has given for businesses in various sectors, our organization, with its trained and expert staff and advanced technological equipment, provides electricity measurement equipment within the scope of IEC 62053-21 standard, static meters (class 0,5) for AC active energy. , 1 and 2) also provide testing services.
