Abstract

As has been previously stated the most positive and reliable type of protection compares the current entering the circuit with the current leaving it; on transmission lines and feeders the length, voltage or arrangement of the line very often make this principle uneconomical so, in a distance relay, instead of comparing the local line current with the current at the far end of the line, the relay compares the local current with the local voltage in the corresponding phase, or suitable components of them.
