FAULT CURRENT LIMITER

摘要

A fault current limiter comprises a contact device to the contacts of which is connected a resistor/inductor combination comprising a series connection of a first and a second resistor as well as a third resistor/inductor connected in parallel with the series-connected resistors. The second resistor consists of a resistor with superconducting properties, dimensioned such that the change from superconducting to normally-conducting state occurs when the critical current density of the resistor is attained.
