LVDC systems - Part 102: Low-voltage DC electric island power supply systems

Scope

IEC TR 63282-102:2025 assesses the existing technical requirements (by TC 64, TC 82, SyC LVDC) and close any gaps related to electric island LVDC power supply systems in rural or remote areas without electricity up to a maximum of 1 500 V only. Additionally, it covers the case of LVDC auxiliary power supply systems for ships.
Specific technical items for electric island LVDC systems are explained in this document. Rationale for the proposed voltage level, topology, power quality, etc. are given.
This document gives inputs to several TCs in charge of the standardization of different issues and coordinated by SyC LVDC.
