The fault-induced transient analysis is an important tool for high-speed fault detection, classification, and location. Therefore, the assessment of the effects of fault parameters such as fault location, resistance, and inception angle in fault-induced transients is quite remarkable for fault diagnosis. In addition, series compensation usually causes fails in conventional protective methods and the investigation of the effects of a series capacitor in fault-induced transients is also important. This paper aims to study the effects of the fault inception angle in the energy of the fault-induced transients in voltages and currents for both
non-compensated and series compensated transmission lines. The features of fault-induced transients are evaluated by means of the wavelet coefficient energy analysis. The faults were simulated in real-time by using the Real Time Digital Simulator and the wavelet analysis was performed offline by using the software Matlab.
