The module of the capacitive energy storage is intended to investigate high-current electrical discharges in dense media. The module is a functionally completed remote-operated capacitive energy storage built on eight capacitor cells with reverse-switching dynistor (RSD) switches. The module comprises a charger with a highfrequency inverter, a protection contactor with normally closed high-voltage contacts to neutralize cell charge, control units of RSD switches, control and diagnostics apparatus with a programmable logic controller. The semiconductor switches in the capacitor cells are triggered by light pulses transmitted from a remote control board via eight fiber-optical cables. Information exchange between the module control and diagnostics system and the remote terminal is also realized via fiberoptical cables. The storage is designed for operation in the programmable discharge mode, when semiconductor switches in the capacitor cells are switched on in the specified time sequence according to the preset program. A maximal current pulse amplitude of 400 kA at the module output is attained during simultaneous discharge of all eight cells in the short-circuit mode. The wave-front of the current pulse is 150 µs. The volume of the capacitor module is 1.3 m 3 .

The capacitor banks are intended for generation of the counter current pulse in vacuum circuit breakers of two-step powerful contactor (switchgears). These switchgears are part of the power supply system of ITER superconductive coils and provide fast discharge of coil magnetic field energy by breaking the coil current supply loop and connecting in the loop the high energy resistors. The superconductive coils of the ITER facility store considerable energy (several gigajoules) and the counter pulse capacitor bank should generate the pulse current not less than 70 kA during about 600 at an initial voltage up to 10 kV. After generation of the current pulse the discharge switch of the capacitor bank closes and a high voltage exceeding the initial voltage (10 kV) is applied to the discharge switch. The paper presents the features of the transients during the commutation cycle, design of the capacitor bank and its main components (semiconductor discharge switch, inductor, charger, control devices, etc.), as well as the results of the capacitor bank testing.
