Abstract
A mechanism for travelling wave protection of a transmission line and a method for acquiring information of both voltage and current polarities from two ends of a transmission line. The method includes comparing the voltage and current polarities of both ends of the transmission line to each other. The method also includes making a trip decision based on the comparison.
