What is EN 60255-24:2020?

EN60255-24:2020 is a technical standard that specifies the requirements for protective relays and protection equipment used in electrical power systems. This standard provides guidelines for testing and evaluating the performance of these devices to ensure their reliability and effectiveness in protecting the power system from faults and abnormal conditions.

Key Requirements of EN60255-24:2020

The standard sets out several key requirements that protective relays and protection equipment must meet:

Accuracy: The devices should accurately measure and analyze electrical signals to detect faults and abnormal conditions.

Speed: The response time of protective relays should be fast enough to trip the circuit breakers and isolate the fault before it causes any significant damage to the power system components.

Reliability: The devices should operate reliably under various environmental conditions and during system disturbances.

Compatibility: The protective relays and protection equipment should be compatible with other devices and systems in the power network.

Safety: The devices should comply with safety standards to protect personnel working on or near the power system.

Testing and Compliance

To ensure compliance with the standard, protective relays and protection equipment undergo rigorous testing procedures. These tests evaluate the devices' performance in detecting different types of faults, their response time, and their ability to coordinate with other protection devices in the system. The results of these tests determine whether the devices meet the requirements set by EN60255-24:2020.

Manufacturers are responsible for ensuring that their products comply with the standard and carry out the necessary testing. Independent testing laboratories may also perform additional tests to verify compliance. Compliance with EN60255-24:2020 provides assurance to users that the protective relays and protection equipment they are using meet industry standards for reliability and performance.
