SF6-Air Monitor for high voltages

SF6-Air Monitor for high voltages

The secondary windings are passed through an SF6 / air bushing into the terminal box. The high voltage connection is implemented via a short-circuit proof aluminium pipe. The current distribution along the insulator is optimised by a special layout of the control electrode inside the silicone composite insulator.
