Inhibitor module and shielding arrangements for high voltage equipment

A shielding arrangement for a piece of high voltage equipment spaced from a neighboring object, where the piece of high voltage equipment has a first electric potential and the neighboring object has a second electric potential, the shielding arrangement comprising a first shield element for connection connected to the high voltage equipment and an inhibitor module arrangement comprising:

• a first string that comprises at least one resistor;
• a second string that comprises at least one capacitor, the first string being physically separated from and electrically connected in parallel with the second string;
• and
• at least one first inhibitor module comprising:
• a first electrical connection terminal at a first end of the module connected to the piece of high voltage equipment;
• a second electric connection terminal at a second end of the module connected to the first shield element;
• and
• a closed interior comprising at least one of the first and second strings electrically connected between the first and the second electrical connection terminals.

A converter station comprising:

• a converter for converting between alternating current and direct current, the converter comprising a plurality of converter valves;
• an enclosure, the converter being enclosed in an enclosure
• wherein at least one of the converter valves is provided with a shielding arrangement;
• wherein the at least one converter valve has a first electric potential and the enclosure has a second electric potential;
• wherein the shielding arrangement comprises a first shield element connected to the at least one converter valve and an inhibitor module arrangement;
• and
• wherein the inhibitor module arrangement comprises:
• a first string that comprises at least one resistor;
• a second string that comprises at least one capacitor, the first string being physically separated from and electrically connected in parallel with the second string;
• and
• at least one first inhibitor module comprising:
• a first electrical connection terminal at a first end of the module connected to the at least one converter valve;
• a second electric connection terminal at a second end of the module connected to the first shield element;
• and
• a closed interior comprising at least one of the first and second strings electrically connected between the first and the second electrical connection terminals.
