【Abstract】 The theory of traveling wave transmission for CT and VT is analyzed in the paper. The model with distributed parameters has been set up and verified by EMTP simulation tests. It is founded that CT and VT can transform the head part of traveling wave without time delay and the output and input signals have the same polarity. The theory can be applied in the traveling-wave based fault location and protection schemes.更多还原
