What is BS EN 60255-151 - Functional requirements for over/under current protection about?
BS EN 60255-151 is a British standard as a part of the IEC 60255 series that specifies minimum requirements for over/under current relays. BS EN 60255-151 includes a specification of the protection function, measurement characteristics, and time delay characteristics.
BS EN 60255-151 defines the influencing factors that affect the accuracy under steady-state conditions and performance characteristics during dynamic conditions. The test methodologies for verifying performance characteristics and accuracy are also included in BS EN 60255-151.
Who is BS EN 60255-151 - Functional requirements for over/under current protection for?
BS EN 60255-151 on functional requirements for over/under current protection is useful for:
- The electrical industry
- The mechanical industry
- Electrical equipment
- The health and safety industry
- Quality control personnel
Why should you use BS EN 60255-151 - Functional requirements for over/under current protection?
Under-current detection guards against load loss in the event of a power outage. Over-current detection prevents over-loading. Overcurrent protection devices are designed to guard against the potentially dangerous effects of overcurrent, such as an overload or a short-circuit current, which causes a fault current.
BS EN 60255-151 provides its users with specifications for the function and performance, requirements for documentation, and instructions for test methods to assess performance and overcurrent/undercurrent elements. Using BS EN 60255-151 guidelines enhances electrical testing, health and safety measures, and high-quality performance for longer service life.
