A wave-like equation describing coupling currents in a flat multi-strand two-layer superconducting cable has been solved to find slowly decaying non-uniform current loops. The maximum time constant of the loop decay is evaluated analytically. Relatio

An equation for inter-strand coupling currents induced in a finite piece of flat superconducting cable by the time-dependent magnetic field directed perpendicular to the cable wide surface is derived. Analytical solution of this equation demonstrates

Characteristic frequencies describing the rates of current decay in N -strand flat two-layer superconducting cables are studied. It is shown that these frequencies when assembled in ascending order form N - 1 simple subspectra. To each of these subsp

A novel continuous model of the flat two-layer superconducting cable is developed aiming to reconcile apparent contradictions of the accepted classical models. It is shown that after certain modifications, parameters and equations of these models can

The quench of a superconducting cable containing a defect and subjected to a current increase is studied. The cable is represented by a model which consists of a strand with a local decrease in the critical current Ic and the rest of the cable lumped

The matrix method was used to investigate the process of current decay in the samples of flat two-layer superconducting cables. The discrete spectrum of eigen-frequencies has been obtained. Each of these frequencies determines the rate of decay of th

Network models of flat two-layer and round twisted superconducting cables and the matrix approach (MA) to their description are considered. The MA implies a self-consistent application of Faraday's and Kirchhoff's equations to all elements of the net

Currents induced by the time dependent magnetic field in short samples of flat two layer superconducting cables are calculated. To simplify the problem, mutual inductances between elements of the cables were neglected, while all self-inductances were
