Abstract

The present disclosure relates to an anti-static apparatus for neutralising an electrostatically charged surface, for example a moving web. The anti-static apparatus comprises at least one positive emitter and at least one negative emitter configured to generate an electric field. The anti-static apparatus also comprises a voltage supply unit for applying a positive voltage to the at least one positive emitter and a negative voltage to the at least one negative emitter. The voltage supply unit is configured to receive an input voltage and comprises a transformer configured to generate an output voltage having a greater voltage than the input voltage. The voltage supply unit also comprises a gas discharge tube connected to the voltage supply unit on a high voltage side of the transformer. The gas discharge tube comprises a breakover voltage configured to refer the voltage supply unit to ground when a voltage on the voltage supply unit exceeds a breakover voltage of the gas discharge tube.
