Applies to the measurement of relays and protection equipment for power system protection, including control, monitoring and process interface equipment used with the systems. For equipment such as electromechanical relays which do not have electronic circuits, immunity and emission tests are not required. Refers to electromagnetic compatibility for apparatus designed for use at industrial locations.
