  • Breaker circuit configurations for multi-terminal DC systems
    Publication number: 20150171615
    Abstract: Multi-terminal DC system interconnection where three DC electrical feeds (18-20) are interconnected is shown. Each terminal of each DC feed (18-20) is connected to each of the other terminals through a breaker circuit (21-23). Hence current flows from one terminal of one DC electrical feed, for example (18), to another terminal feed, for example (19), through one breaker circuit (21) rather than two breaker circuits with prior art techniques.
