Grounding transformer basics
WebA grounding transformer has another name that is the earthing transformer. The grounding transformer belongs to the auxiliary transformer used in three-phase … WebThe Zigzag grounding transformer is a commonly used option. It is a three-phase, dry-type, air- cooled auto-transformer with no secondary winding. Each phase has two identical windings, which are wound in opposite directions to give the high impedance to normal phase currents. The
