ˈrupturing, vbl. n.
[f. rupture v. + -ing1.]
1. Bot. (See quot. 1839.)
1839Lindley Introd. Bot. 226 Rupturing consists in a spontaneous contraction of a portion of the pericarp, by which its texture is broken through. 1862Darwin Orchids i. 12, I will not affirm that the rupturing of the exterior membrane of the rostellum takes place spontaneously.
2. attrib. rupturing capacity Electr. Engin., a measure of the ability of a circuit-breaker to withstand the surge produced by its operation.
1916C. C. Garrard Electr. Switch & Controlling Gear ii. 54 The remaining considerations which determine the rupturing capacity of an oil circuit breaker apart from size, robustness, quickness of break and, of course, the quality of the oil used, are length and number of breaks under oil, or speaking generally the capability of the switch to bring a large quantity of oil into intimate contact with the arc so as to smother the same as effectively as possible. 1930Engineering 24 Jan. 97/3 These circuit breakers were designed for a rupturing capacity of 1,000,000 kva. 1970J. Shepherd et al. Higher Electr. Engin. (ed. 2) xvii. 560 It is normal practice to specify the rupturing capacity of circuit breakers in kilovolt-amperes or megavolt-amperes. This practice is well established but may be criticized as not being logical, since the breaking capacity in megavolt-amperes is obtained from the product of short-circuit current and recovery voltage. |
