Description
Resonantly grounded power systems require faultcurrent limitation in order to meet current standards and to
ensure personal safety. A current limiting transformer (CLT),
based on an isolating transformer, is investigated here. The major
advantages of a CLT, compared to an isolating transformer, are
power derating, reduction of leakage reactance and thus reduced
losses and reactive power demand during operation.
MATLAB/Simulink® is used to investigate the electrical behavior
of the CLT. Simulations of a phase-to-ground fault are made to
proof the reduction of fault currents. Modelling the CLT in
symmetric components demonstrates the blocking mechanism for
the zero-sequence currents. In this context special attention has to
be paid to resonant currents in resonantly grounded networks,
when using the CLT.
