Abstract
A voltage measurement is made between two points in a circuit. If the measured voltage exceeds a predetermined amount, a switch is operated to electrically connect the two points.
Claims22
An electrical arc extinguishing device for an electrical distribution system, the arc extinguishing device comprising:
- a determiner arranged to:
- receive information about a voltage provided by the electrical distribution system between first and second points in the electrical distribution system;
- determine from the received information whether the voltage provided by the electrical distribution system is indicative of the presence of an electrical arc in the electrical distribution system;
- and
- a short circuiting device arranged to short circuit the first point to the second point in the event that the determiner determines that the voltage provided by the electrical distribution system is indicative of the presence of an electrical arc.
