Scope: This Guiding Technical Conditions recommends procedures for evaluating the level of disturbance emitted by installations, equipment and systems installed in non-public power grids in industrial environments, and is limited to low-frequency conducted disturbances in power supply. On this basis, the relevant emission limits can be obtained, which are suitable for AC 50/60Hz medium and low voltage non-public power grids. Power grids such as shipping, aviation, offshore platforms, and railways do not fall within the scope of this technical guidance document. This guiding technical document describes the low-frequency conducted disturbances emitted by equipment connected to the power supply. These disturbances include: - Harmonics and interharmonic waves; - Unbalance; - Voltage changes; - Voltage sags.
