Equipments Used in HVDC Transmission System | Electrical ... transformers are either single phase units, or three-phase units with either two winding type or three winding type. These are specially designed so as to withstand direct voltage stresses. Moreover, in a converter transformer the currents flowing through the winding have high harmonic contents. Thus the eddy current losses are high.[email protected]
