The EN 60255-24:2020 standard is a professional technical specification that
is widely used in the electrical industry. It provides guidance on the
testing and performance of protective relays and relay systems. This
technical article aims to explain the key aspects and importance of this
standard in the field.
Understanding the Purpose
One of the primary purposes of the EN 60255-24:2020 standard is to ensure
the reliable operation of protective relays. These relays play a crucial
role in safeguarding power systems by detecting abnormalities, faults, and
dangerous conditions. By adhering to this standard, manufacturers and
engineers can design, test, and evaluate the performance of these relays,
thereby enhancing the overall system reliability.
Key Requirements and Tests
The standard specifies various requirements and tests that must be
conducted on protective relays. These include but are not limited to:
performance testing, verification of stated specifications, endurance
testing, thermal and mechanical stress testing, and electromagnetic
compatibility (EMC) testing. Meeting these criteria ensures that the relays
meet industry-wide quality and safety standards.
Significance for the Industry
The EN 60255-24:2020 standard holds significant importance for the
electrical industry as a whole. It promotes consistency and reliability in
the design, production, and use of protective relays, resulting in safer
and more efficient power systems. Compliance with this standard enables
manufacturers to demonstrate the quality and reliability of their products,
while also providing users with confidence in the performance of these
critical devices.
