Abstract
A high voltage switch for switching capacitor banks in and out of a circuit. The switch includes two sets of contacts to perform the switching function. An impedance element is connected in parallel with one set of contacts. Upon closing of the switch current is caused to flow through the impedance element and one set of contacts, thereby preventing the switch from functioning as a short circuit. Subsequently, the second set of contacts engages and the switch can function as a short circuit to completely switch a capacitor bank into the circuit.
