ABSTRACT:
An improved electrostatic shield assembly for power transformer windings provides a decreased shield to winding insulation spacing. The decreased spacing substantially improves the capacitive coupling between the windings and shield, reducing transient voltage oscillations within the windings caused by external lighting surges.
