Abstract
1,062,893. Circuit breaker testings. A. REYROLLE & CO. Ltd. Nov. 29, 1963 [Dec. 4, 1962], No.45866/62. Heading G1U. A synthetic circuit breaker testing circuit of the series type is modified by including a length of transmission line in order to simulate the short line fault condition. In the basic series circuit shown, the test circuit breaker T is in series with a heavy current 50 c/s generators, a high voltage high frequency circuit including a source capacitor C s and a restriking transient capacitor C, connected as shown or in parallel with the auxiliary circuit breaker A. When the auxiliary breaker A is closed a heavy 50 c/s current flows. Shortly before the test breaker opens to break the current the switch G is closed and a 500 c/s current flows in the breaker, reaching zero together with the main current. When the power arc clears, the correct voltage transient is imposed across the breaker by the capacitor C,. The transmission line may be short circuited at its far end and its near end used as a link in either the low frequency or high frequency circuit, or it may connect either the capacitor C r , the test circuit breaker T or the high frequency circuit L 2 , G, C s with the rest of the circuit Figs. 2 to 13 (not shown).
