Load Calculation & Balancing

In three phase distribution system the unbalance phenomenon occurs due to single-phase loads and unequal sharing of loads in each phase. To overcome this problem, distribution systems require equal sharing of load in each phase. This is possible by three phase load balancing technique. The result of the proposed hardware and simulation shows that microcontroller and relays switching is effective in reducing the unbalancing in three phase lines and also reducing the current in the neutral wire of the system. In addition, it retains voltage regulation and stability in the all three phase.
