摘要：The invention relates to a method and arrangement for reducing to a minimumthe electrical alternating fields generated in the surroundings of a visual display unit (1).The visual display unit includes a voltage connected part (5), on which undesirable voltagevariations occur. A smoothing high voltage capacitor (C3) of high capacitance is connectedto the voltage connected part (5). Connected between the high voltage capacitor (C3)and earth is a compensating circuit (20) which functions as a negative capacitor whosecapacitance is greater than the capacitance of the high voltage capacitor (C3) by a givenfactor.
