The selection and applications of protective relays and their associated schemes shall achieve reliability, security, speed and properly coordinated. These standards guide technicians in performing essential tests to prevent equipment damage and outages. Acceptance testing, commissioning, and startup will include control power tests, current transformer and potential transformer tests, and any other device testing associated with the protective. Traditional protective relay books are written by engineers as a resource for engineers to use when modeling the electrical system or creating relay settings, and they often have very little practical use for the test technician in the field. For professionals working in utilities, industries, or renewable energy systems, understanding these standards is not optional—it is essential.
