ABSTRACT IMPROVEMENT IN CAPACITIVE VOLTAGE TRANSFORMERS WITH ELECTRONIC OUTPUT The invention concerns capacitive voltage dividers having an electronic amplifier connected to the terminals of a capacitor of the divider In order to overcome the problems which arise due to the existence of charges which are trapped in the divider when the supply to the latter is interrupted, there is provided a means for disconnecting the amplifier. The disconnecting means is controlled by a signal depending on a voltage at the terminals of a capacitor of the divider and the current through the divider. Use for capacitive transformers for measuring high voltages.
