EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of IEC EN 60255-4 testing. IEC EN 60255-4 is an international standard for single-input energizing quantity metering relays with a dependent specified time. This standard provides guidelines for the design, testing, and performance of relays that measure energizing quantities such as voltage, current, or frequency and use a specified time delay before actuation.
The standard applies to relays used in a wide variety of applications, including power systems, protection systems and control systems. These relays are designed to detect abnormal conditions in the system and initiate appropriate actions such as tripping a circuit breaker, opening a contactor or triggering an alarm.
The standard specifies performance requirements for energizing quantity metering relays, including accuracy, precision, repeatability, and stability. It also provides guidance on the design and construction of these relays, including requirements for the electrical, mechanical and environmental characteristics of the relay.
In addition, the standard defines the test procedures that must be used to verify the performance of energizing quantity metering relays. These tests include accuracy, precision, stability and durability tests and are designed to ensure that relays meet the requirements of the standard and are suitable for the intended application.
Overall, IEC EN 60255-4 provides a comprehensive set of guidelines for the design, testing, and performance of single-input energizing metering relays with a dependent designated time and serves as a valuable resource for engineers, technicians, and other professionals.
