Abstract

Sensored bushing (1) for medium or high voltages, the bushing comprising a) a bushing body (140); b) an elongated bushing conductor (560); c) a tubular sensing electrode (170), arranged coaxially around the bushing conductor, so that the sensing electrode and the bushing conductor are operable as electrodes of a primary capacitor of a voltage divider for sensing the voltage of the bushing conductor; d) a tubular shield electrode (190), arranged coaxially around the sensing electrode (170); e) a spacer (200), arranged radially between the sensing electrode (170) and the shield electrode (190) and mechanically connected to the sensing electrode and to the shield electrode to maintain the sensing electrode and the shield electrode in a fixed spatial relation to each other.
