Title: What is EN 61851-24: 2020 and EN 60255-26: 2020? A Technical Overview

The electrical industry demands the highest level of reliability and safety for the equipment it controls. To achieve this, various technical standards must be adhered to. Two such standards are EN 61851-24: 2020 and EN 60255-26: 2020. In this article, we will provide an overview of these two standards and their significance in the field of electrical engineering and power systems.

EN 61810-1: 2020: The Ultimate Relay Standard

EN 61810-1: 2020 is a widely recognized technical standard developed by the European Committee for Electrotechnical Standardization (CENELEC) for relay devices used in electrical equipment. This standard aims to establish consistent requirements for different types of relays, such as electromechanical, solid-state, or hybrid relays. By defining these requirements, EN 61810-1: 2020 ensures that manufacturers produce reliable and compliant relay devices that meet specified performance levels.

Key Requirements and Guidelines

EN 61810-1: 2020 establishes key requirements and guidelines for relays, including their electrical, mechanical, and thermal properties. The standard defines the testing procedures for the relays, which are essential for ensuring their performance and reliability.

EN 60255-26: 2020: The Key Relay Standard

EN 60255-26: 2020, also known as IEC 60255-26: 2020, is a professional technical standard for protective relays used in electrical power systems. This standard specifies performance requirements and test procedures for these relays under different operating conditions and system faults.

The primary purpose of EN 60255-26: 2020 is to ensure the proper functioning and accuracy of these relays. By following this standard, manufacturers can design relays that meet certain performance criteria, making them reliable and effective in protecting power systems from various abnormalities such as overloads, short circuits, and voltage fluctuations.

EN 60255-26: 2020 Test procedures

EN 60255-26: 2020 outlines a set of test procedures for evaluating the performance of protective relays. These procedures are designed to verify that the relays meet the requirements specified in the standard.

Conclusion

EN 61851-24: 2020 and EN 60255-26: 2020 are two crucial technical standards that must be adhered to for reliable and safe control of electrical power systems. These standards provide guidelines for manufacturers to design and test relays that meet specific performance criteria. By following these standards, engineers and technicians can ensure that the electrical equipment they control is safe, reliable, and effective in protecting power systems from various abnormalities
