Abstract
PURPOSE: To protect a coil from damage by providing a DC-field releasing layer in adjacent to an AC-field releasing layer thus preventing Dc surface sicharging.
CONSTITUTION: A stator coil 1 is inserted into a slot 5 to form a main insulation layer 2 and low resistance corona shield 3. An AC-field releasing layer 4 and a DC- field releasing layer 3 in adjacent to the former are provided at the coil end, thus stator coil can be protected from the damage due to the surface discharge by releasing the DC-field together with the AC-field generated at the coil end.
