WebNov 10, 2024 · In this paper, a fault protection diagnostic scheme for a power distribution system is proposed. The scheme comprises a wavelet packet decomposition (WPD) for signal processing and analysis and a support vector machine (SMV) for fault classification and location. The scheme is tested on a reduced Eskom 132 kV power line. The WPD is … Webbreaker-and-a-half switchyard schemes are preferred for transmission switchyards. Three terminal lines are generally not considered acceptable. For generation interconnections, a line tap is not considered acceptable. There may also be instances when it is not considered prudent or practical to further extend an existing ring bus. thai beauty ginger plant
