摘要： A high-voltage generator of an X-ray apparatus comprises a high-voltage measurement device. The measurement device comprises a compact component comprising both the measurement resistor and a film capacitor used both to protect said resistor and eliminate the parasitic effects induced by parasitic capacitances of the generator. The film capacitor is made in insulating films by a sequence of metalized strips and insulating strips. The films are positioned relative to one another in such a way that the film capacitor is formed by series-mounted discrete capacitors. To this end, between two successive films, the width of the bottom strips of the film crosses two metalized strips of the top film.
