Abstract

PURPOSE: To promote a simplification of the circuitry and an improvement of protective performance, by conducting a measurement value of original wave form of voltage and current in the system, further by applying only one information either current or voltage from the remote end as well as by considering the power transmission line as distributed constant circuit.
