What is IEC 62059-1:2012 Ed.3 (2018)?

The International Electrotechnical Commission (IEC) is a global organization that sets international standards for electrical, electronic, and related technologies. These standards provide guidelines and specifications to ensure the safety, reliability, and efficiency of various products and systems.

IEC 62059-1:2012 Ed.3 (2018) is one such standard that specifically addresses the electricity metering equipment known as Power Quality Measurement Equipment (PQME). This standard defines the requirements and test methods for PQME devices used in power systems.

Purpose and Scope of IEC 62059-1:2012 Ed.3 (2018)

The primary purpose of IEC 62059-1:2012 Ed.3 (2018) is to establish uniformity in the measurement and assessment of power quality parameters. Power quality refers to the characteristics of electrical power in terms of voltage, frequency, and waveform, among other aspects.

Power quality issues can have significant implications for both electrical utilities and consumers. Poor power quality can result in malfunctions or damage to sensitive electronic equipment, as well as increased energy consumption and economic losses. Therefore, it is crucial to have reliable and accurate PQME devices to monitor and assess power quality effectively.

Main Requirements of IEC 62059-1:2012 Ed.3 (2018)

IEC 62059-1:2012 Ed.3 (2018) specifies the minimum performance requirements and testing procedures for PQME devices. These requirements include:

- Voltage measurement: The standard outlines the acceptable measurement limits for voltage fluctuations, asymmetry, unbalance, and harmonic distortion.

- Current measurement: It specifies the requirements for measuring current harmonics and the accuracy limits.

- Communication interfaces: The standard defines the necessary communication protocols, such as Modbus or Ethernet, for data transmission between PQME devices and other systems.

- Accuracy and performance: IEC 62059-1:2012 Ed.3 (2018) lays down the criteria for accuracy, stability, and response time of PQME devices.

- Calibration and verification: The standard provides guidelines for calibration procedures and equipment verification to ensure the accuracy and reliability of the measurements.

Conclusion

IEC 62059-1:2012 Ed.3 (2018) plays a vital role in ensuring the quality and reliability of power supply systems. Compliance with this standard enables accurate measurement and assessment of power quality parameters, facilitating the detection and mitigation of power quality issues. By adhering to the requirements and testing procedures outlined in IEC 62059-1:2012 Ed.3 (2018), electrical utilities and consumers can enhance the efficiency and safety of their power systems, ultimately contributing to improved overall power quality.
