Voltage balancing in low‐voltage radial feeders using Scott transformers
IET Generation, Transmission & Distribution, 2014 Increasing use of heat pumps, micro‐generation, electric vehicles and energy‐saving technologies is expected to cause severe voltage imbalance on low‐voltage (LV) radial feeders and deteriorate the power quality seen by single‐phase (1Φ) and three‐phase (3Φ) LV connected consumers. To solve this problem, a Scott transformer‐based balancing technique is
