leakance Electr.|ˈliːkəns|
[f. leak v. + -ance as a shortening of leakage conductance.]
Conductance attributable to leakage or imperfect insulation.
1893O. Heaviside Electromagn. Theory I. 453 A process..of representing a large number of separate leaks by uniform leakance. Ibid., Distribute the inductive leakance uniformly, in imagination, of course. 1928Bradfield & John Telephone & Power Transmission ii. 18 Since the insulation of the circuit..can never be perfect, there must be a certain leakance from wire to wire,..stated in ‘mhos’, or sometimes in ‘micro-mhos’ per mile of loop. Ibid. iv. 55 The leakance of aerial circuits varies irregularly between wide limits, owing to weather and other conditions. 1962Newnes Conc. Encycl. Electr. Engin. 845/1 Leakance and capacitance effects are large [in telecommunication lines], so that the attenuation is much higher than could be tolerated in power transmission. |
