This post was last edited by yuchenchf on 2015-8-4 11:14. Reward for participation: 3 Wealth. Reward for correct answer: 10 wealth. For a three-phase motor, with a rated voltage of 220V per phase winding, and a line voltage of 380V for a symmetric three-phase power supply, what voltage should be used for the three-phase windings? A. Star connection, without a neutral wire; B. Star connection, with a neutral wire; C. Both A and B are possible; D. Delta connection. New activities have started in the production area – great prizes are available, so hurry and participate: 【Production Over Summer】The production area has entered the “train during the hot summer days” mode
