On September 25, RRA published the Notification number KOR/858, to consult about the Technical Regulation for Electromagnetic Compatibility. The final Date for Comments is November 23, 2019.
The main points are as follows:
-Adoption of international standards to alleviate EMI limits for electric railways in the frequency range 9 kHz to 150 kHz and establishment of EMS standards by supplementing the electromagnetic immunity (Article 10, Annex 7).
-Removal of EMI limits between frequency range 9 kHz to 150 kHz Extension of the measurement frequency range of radiated disturbance for enclosure ports of in-vehicle devices in electric railways
-Extension of the measurement frequency range of electromagnetic immunity of in-vehicle devices in electric railways.
-Changes of performance criteria for electrical fast transient/burst test of fixed railway power equipment.
-For successful avoidance of EMC problems due to the introduction of lighting equipment integrated with information and communication technology, the adoption of international standards and the establishment of EMI limits (Article 9, Annex 6).
-Extension of measurement frequency range for radiated disturbance frequency range for enclosure port.
– Establishment of EMI limits of a loop antenna for lighting equipment exceeding 1.6 m, the limit of extra-low voltage (ELV) lamp and current probe measurement, respectively.
