Abstract:
A resistor assembly (80) for dividing an applied voltage into an intermediate voltage being below the applied voltage, said resistor assembly (80) comprising:an insulating substrate, (52); a resistive voltage divider including a first and a second resistive layer (54, 56) provided on said insulating substrate, (52); and an additional resistive network (74) with a first network terminal (69) and a second network terminal (71), the said additional resistive network (74) being coupled in series with said first resistive layer (54), wherein said additional resistive network (54) includes at least two resistive portions (76,78,79) which are releasably coupled to said first and second network terminals via at least one bridge connection (82), each bridge connection (82) having a resistance which is substantially lower than a resistance of said at least two resistive portions for adjusting a predetermined ratio of said resistive voltage divider, and wherein a first resistive portion (76) and a second resistive portion (78) have substantially different resistance values for selecting a predetermined resistance value from a range of resistance values of said additional resistive network (74).
