Vibration of Bundled Conductors Following Ice Shedding [PDF]
IEEE Transactions on Power Delivery, 2008 The dynamic behavior of bundled conductors following ice shedding from one subconductor is examined numerically using the finite-element method. An existing model of ice shedding from a single conductor is improved by developing a model of spacers which connect subconductors in the span.
