This Part of GB/T 24338 specifies the electromagnetic emission and immunity requirements for fixed power supply electronic and electrical apparatus and systems in the railway system, including the apparatus power supply, the apparatus own protection control circuits, as well as substations, autotransformers, booster transformers, substation switch cabinets, local electrical switches, and other trackside apparatus. This Part does not apply to filters of which the operating voltage is the traction power supply voltage (e.g., filters for harmonic suppression or power factor compensation). Usually the filter requires a separate enclosure and access regulations. If there is electromagnetic emission limit requirement, it will be specified in the electronic apparatus standard.
