| Zusammenfassung: | According to an embodiment, a fault point location method of locating a fault point by using a voltage and a current of each terminal of a transmission line to be located and a transmission line constant is disclosed. According to the method, a formula simplified by a secondary approximation using an approximation of a hyperbolic function from a basic equation of a distributed constant circuit equation using the hyperbolic function or a formula simplified by a division of both sides by the hyperbolic function is determined. A location distance from a predetermined end of the transmission line to the fault point is calculated by using the simplified formula. |
