Features

1. High performance & reliability
  • 100 times current-limiting performance of superconducting current-limiting module
  • Securing operation reliability of the high-speed impedance unit
  • Automatic recovery within a few minutes after operation, and can be used repeatedly
2. Flexibility
  • Flexible applicapability to various ratings using modular design of units
  • Securing ease of installation and space utilization by separating the superconducting unit and the high-speed impedance unit
3. Compactness
  • Realization of system miniaturization and light weight by application of high-speed switch (FS) and current limiting resistance (CLR)
  • Integrated cryocooling of a superconducting unit using subcooled LN2 for three-phase operation
4. User-friendly design
  • Key parts can be maintained when the front door is opened
