Abstract:
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 μs-50 ms.
