Three-phase unbalance refers uneven distribution of voltage, current or load in a three-phase system. This is caused by unbalanced loads, grid faults, unbalanced power supplies, line faults, or bad equipment. Imbalances cause voltage fluctuations, power loss, equipment overheating, and reduced motor efficiency. SUAR produced by SANHE automatically adjust three-phase unbalance, using balanced reactor technology. Three-phase current is balanced by providing or absorbing reactive power. It balances asymmetry of voltage and current, reduce the power loss.
