The two traveling arms are retractable and rotatable and are supported by two wheels, and the centers of gravities of the two traveling arms can be adjusted by a box body in a sliding manner; when a tower frame is crossed, one traveling arm is used as support, the other traveling arm ...
Transmission linesDynamic state estimation DSETraveling wavesFault locationA dynamic state estimation (DSE) approach is proposed to improve the accuracy to identify the front-wave arrival times of a two-terminal traveling wave protection scheme for a transmission line with low sampling rates. The ...
Furthermore, all derived results were verified by putting them back into the assumed equation with the aid of Maple software. Further, the conservation laws of NLETLs are computed by the multiplier method. Keywords: nonlinear low-pass electrical transmission lines; modified khater method; multiplier...
