LVDC systems. Assessment of standard voltages and power quality requirements. | Status: Current

1 Scope The purpose of this document is to collect information and report experience for the standardization of voltage levels and related aspects (power quality, EMC, measurement, etc.) for LVDC systems (systems with nominal voltage up to and including 1 500 V DC). Rationale for the proposed voltage values is given. Variation of parameters for the voltage (power quality) for their boundaries are defined. Nevertheless, some of the technical items are not exhaustively explained in this document and some gaps are identified for future work. Attention is paid to the definition of DC voltage. Systems in which a unipolar voltage is interrupted periodically for certain purposes, e.g. pulse voltage, are not considered. Traction systems are excluded from this document. This document gives technical inputs to TCs in charge of the standardization of different issues and coordinated by SyC LVDC.
