A novel Wye-wye transformer design for active system grounding. is described in this paper. Proposed as a solution to improve the ground fault performance in distribution line networks. the zero-sequence flux developed in the magnetic core of a transformer is on a ground fault harvested by coils wound around three limbs. https://www.kaliboat.com/product-category/food-servicecommercial-kitchen-equipmentfood-preparation-equipmentother-commercial-food-prep-industrialrestaurant-business-9/
