Abstract: A power delivery system comprises a main circuit controller and a plurality of branch circuits that are in parallel with each other and in series with the main circuit controller. Each branch circuit has its own branch circuit breaker that can be opened to disconnect the associated branch from the remainder of the system. The main circuit controller comprises normallyconducting, current-limiting interrupting means and a resistor shunting said interrupting means. Means responsive to fault current through said main circuit controller and any one of said branch circuit breakers causes the interrupting means to operate with a current-limiting action that diverts the main circuitcontroller current from the interrupting means into the shunting resistor. Means responsive to said fault current causes said one branch circuit to open while the main circuit-controller current is following a path through the shunting resistor. The interrupting means of the main circuit controller is reclosed immediately after the branch circuit breaker opens and interrupts the current therethrough. The resistor has an impedance no higher than about 18 percent of normal load impedance but sufficiently high to limit fault current therethrough under short circuit conditions to a value such that the current through any of said branch circuit breakers is within the maximum currentinterrupting capacity of the branch circuit breaker.

Abstract: A high voltage electric circuit breaker comprising a high potential tank mounted atop an insulating column. Opening of the circuit breaker is initiated by an operator located atop the insulating column in a housing filled with high dielectric strength fluid. The operator is maintained at ground potential by electroconductive structure extending vertically through the column between the operator and the base of the column. The operator is connected to control means within the high potential tank by a short operating rod of insulating material that extends through said dielectric fluid.

Abstract: Discloses an extra-high speed circuit breaker in which the force for initial contact-separation is supplied by an electrohydraulic shock wave generator. A follow-up operator is triggered into operation by the electrohydraulic operator to continue contact-separation after the electrohydraulic operator has lost its initial effectiveness.

Abstract: A circuit breaker comprising spaced-apart, high voltage enclosures respectively mounted atop spaced-apart insulators, circuit interrupters within the enclosures, and control valves respectively associated with the interrupters for controlling their operation. The control valves are interconnected by a mechanical linkage for simultaneously operating the control valves. The linkage comprises a force-equalizing coupling, the parts of which can change position slightly in response to minor shifting of one enclosure relative to another without imparting motion through said linkage to any of said control valves.
