Abstract

A filter for an HVDC system. The filter includes a capacitor and a reactor arranged in an indoor location having a first space for erecting filter components. The first space includes a high voltage area and a low voltage area defining a first electric potential direction.

Claims

1. A filter for an HVDC system, the filter comprising:

a capacitors, and

a reactors,

wherein the capacitor and the reactor are arranged in an indoor location comprising a first space for erecting filter components comprising a high voltage area and a low voltage area defining a first electric potential direction, wherein the location further comprises a second space for erecting filter components having a low voltage area and a high voltage area defining a second electric potential direction, and wherein the first electric potential direction at least in part is adverse to the second electric potential direction.

2. The filter according to claim 1, wherein the high voltage area of the first space is positioned adjacent the high voltage area of the second space.

3. The filter according to claim 1, wherein the first space and the second space overlap, whereby the high voltage area of the first space is common with the high voltage area of the second space.

4. The filter according to claim 1, wherein the second space is located on top of the first space.

5. The filter according to claim 1, wherein the capacitor is suspended from a ceiling in the second space.

6. The filter according to claim 1, wherein the reactor is positioned on a shelf in the second space.

7. The filter according to claim 1, wherein the filter comprises a resistor which is positioned on a shelf in the second space.

8. A method for providing a filter for an HVDC system, the filter comprising a capacitor and a reactor arranged in an indoor location comprising a first space for erecting filter components having a high voltage area and a low voltage area defining a first electric potential direction, the method comprising:

providing a second space for erecting filter components having a low voltage area and a high voltage area,

defining a second electric potential direction, and

orienting the second space such that the first electric potential direction becomes at least partly adverse to the second electric potential direction.

9. The method according to claim 8, further comprising:

positioning the high voltage area of the first space adjacent the high voltage area of the second space.

10. The method according to claim 8, further comprising:

locating the second space on top of the first space.

11. The method according to claim 8, further comprising:

arranging the high voltage area of the first space and the high voltage area of the second space in common.
