The invention is concerned with an inhibitor module arrangement, a shielding arrangement comprising an inhibitor module and a converter station comprising a converter and a shielding arrangement. The inhibitor module arrangement comprises a first string, a second string, and at least one first inhibitor module (), where the first string comprises resistors (R), the second string comprises capacitors (C, C, C), the first string is physically separated from and electrically connected in parallel with the second string and the at least one first inhibitor module () comprises a first electrical connection terminal () at a first end for connection to a piece of high voltage equipment, a second electric connection terminal () at a second end for connection to a first shield element for this piece and a closed interior comprising at least one of the strings electrically connected between the first and the second electrical connection terminals ().

Inhibitor module and shielding arrangements for high voltage equipment

A shielding arrangement can be provided for a piece of high voltage equipment spaced from a neighboring object. The piece of high voltage equipment has a first electric potential and the neighboring object has a second electric potential. The shielding arrangement includes a resistor, a shield element for connection to the high voltage equipment via the resistor, and a capacitor connected in parallel with the resistor. A resistance of the resistor and a capacitance of the capacitor together define a time constant in a range of 10 &#x3bc;s-50 ms.

Shielding arrangement for high voltage equipment

A cable for winding of an electromagnetic device. The cable includes a conductor, and a layer including a magnetic material having a relative permeability in the range 2 to 100000, wherein the layer at least partly surrounds the conductor.
