US 2010/0246085 A1 · HIGH-VOLTAGE DEVICE

Abstract

A high-voltage device includes a conducting element for conducting a high-voltage current and at least one transient reducing unit for reducing voltage peaks of existing propagating very fast transients (VFTs) by the generation of arcing. The transient reducing unit has at least one arcing occurrence surface. The at least one arcing occurrence surface of the at least one transient reducing unit is positioned in the vicinity of the conducting element such that arcing occurs between the transient reducing unit and the conducting element when the potential difference between the transient reducing unit and the transient conducting element is above a threshold value, such as at the occurrence of a very fast transient. A method is also provided for equipping a high-voltage device with the transient reducing unit.

Dependent claims

A high-voltage device comprising:

a conducting element for conducting a high-voltage current;
and
at least one transient reducing unit for reducing voltage peaks of existing propagating very fast transients by the generation of arcing, the at least one transient reducing unit having at least one arcing occurrence surface and at least one permanent electric contact portion being conductively connected to the conducting element,
wherein the at least one arcing occurrence surface of the at least one transient reducing unit is positioned in the vicinity of the conducting element to enable arcing to occur in a gap located between the at least one transient reducing unit and the conducting element when a transient potential difference between the at least one transient reducing unit and the conducting element is above a threshold value.
