The purpose of this publication is to collect information and report experience in order to make recommendations for standardization of voltage levels and related aspects (power quality, EMC, measurement …) for LVDC systems (voltage lower than 1500 V). Rationales for the proposed voltage values are given. Parameters for the voltage (power quality) and recommendation for their boundaries are defined. Some of the technical items may not be exhaustively explained in this document and some gaps may be identified for future work. Attention should be paid to the definition of DC voltage. It permits the existence of systems in which a unipolar voltage is interrupted periodically for certain purposes, e.g. pulse voltage, these systems are not considered. NOTE: Traction systems are excluded from this document.
