Fault-Current Limiters |
||||
| High fault-currents caused by
lightning strikes are a troublesome and expensive
nuisance in electric power grids. One of the near-term
applications for high temperature superconductors may be
the construction of fault-current limiters which operate
at 77K. The need is to reduce the fault current to a
fraction of its peak value in less than a cycle (1/60 sec).
A recently tested fault-current limiter can operate at 2.4 kV and carry a current of 2200 amperes. It was constructed from BSCCO material. |
