Superconductive inductors with energy storage capacity in the range of 1000 to 10,000 MWh are under study to provide peak shaving and load leveling in power systems. Because of their large size - which is dictated by the economic considerations - it is of great concern to have an estimate of the eddy current losses to prevent the superconductor from going into the normal state. Also, because of the low damping and the large sizes, it is important to inquire as to the effects of external system disturbances such as faults and switching on the internal transient voltages and currents. Some preliminary results are presented and a need for a more detailed analysis is discussed. It is shown that the insulation stress caused by a fault can be greatly minimized by the presence of an electrostatic shield. The rate of change of current in the unshielded case is 15 times the normal.
