Abstract
Disclosed is a positive sequence undervoltage distance relay that forms a part of a relay system that provides protection for a high voltage three phase transmission line. The undervoltage distance relay provides a high speed blocking function for use with the high speed tripping functions in the protective relay system. In one embodiment the undervoltage distance relay utilizes the positive sequence components of the three phase transmission line. In another embodiment the undervoltage distance relay utilizes the line to ground (or line to line) voltages and currents of the three phase transmission line.
