Inductive Test Circuit for a Fast Acting HVDC Interrupter

A unique test facility utilizing the inductive energy storage principle has been constructed in order to examine the characteristics of a fast acting HVDC interrupter. The facility is capable of producing currents up to 10, 000 A, developing voltages up to 200 kV, and storing energies up to 125 kJ. It is able to closely simulate the operational stresses encountered in the interruption of dc current. Experimental and computer results illustrate the operating characteristics of the facility.
