Abstract : A theoretical analysis is presented for the propagation of the normal region in a series wound superconduting coil without protective circuitry. The propagation of the normal region is expressed as a variable resistance with time, which then allows the soution of the electrical circuit equations to yield the current, voltage across the normal region and the local energy dissipation during the decay transient. Good agreement of the predicted currents and voltages with experimental results is obtained. The effect of coil energy, as well as metal coating on the conductor on the voltages and on the energy dissipated per unit length of wire at the initial normal point during the deay transient, are evaluated.
