Title: Improved arrangement for testing electric switchgear

Abstract: 1,005,942. Testing circuit breakers. LICENTIA PATENT-VERWALTUNGS G.m.b.H. Sept. 27,1962, No. 36760/62. Heading_G1U. An arrangement for testing circuit breakers comprises a circuit branch containing an A.C. power source and another branch containing a second source of electrical oscillations of higher frequency than those from the first source. The two sources are each individually series connected with a switch and are each parallel connected across the breaker to be tested, a unidirectional current carrying device being connected in each branch to stop the voltage front produced in the other branch. In the embodiment described for testing the circuit breaker P the A.C. power source G is included in a circuit including an inductor L, a capacitor K 1 , and a switch H. In parallel with the switch H is a series arrangement of a diode G H , capacitor C H  and inductor L H . The other circuit connected across the breaker P is designed to produce oscillations whose frequency is higher than that of the power source G. Two spark gaps F 1 , F 2  are included and the striking of these is controlled by a device St in response to a signal derived from a saturable current transformer W coupled to the power circuit. Also included in the circuit are two capacitors C and K 2 , (which sets the frequency), an inductance Ls and a diode Gs in parallel with the spark gap F 1 . In operation, the switch H is opened so that a steep fronted recovery voltage is applied through the diode G H  to the circuit breaker P. When the current is in the oscillation branch passes through zero a voltage is applied from the capacitor K 2  through the diode Gs to the circuit breaker, this voltage rising slowly at first but becoming predominant after a short interval. This arrangement simulates the conditions which may be expected when a breaker is operated on duty, where the characteristics of the wave front appearing across the breaker contacts are determined by the power source and by the line portion between the fault and circuit-breaker.
