| titleOfInvention | Transmission line fault current detection device, fault section detection method and device |
| abstract | (57) [Summary] (Correction) [Purpose] Even if the combined output of multiple magnetic sensors provided for measuring fault current such as zero-phase current or short-circuit current cannot be set to zero, only fault current can be easily extracted. To provide a method and an apparatus that enable accurate detection of a faulty section even in a multi-rail combined tower. [Structure] Fault current measuring means 100 arranged at appropriate intervals along a power transmission line, delay means for delaying an output signal of the fault current measuring means by N / 2 cycles (N is a positive integer), and the fault current. An arithmetic means 32 is provided for adding and subtracting the output signal of the measuring means and the signal delayed by N / 2 cycles so as to cancel the output signal of the power transmission line in the normal state. |
