Electrical faults due to leaning trees have been studied in [1]-[2] and it was found that the initial transients due to the associated arc reignitions are behavioral traits. These transients have been localized using the discrete wavelet transform (DWT). In this paper, these features are extracted from residual voltages using DWT. Therefore, the fault localization is carried out. The term for locating...
In this paper, the initial transients in the electrical network due to arc reignitions associated with high impedance faults caused by leaning trees are extracted from phase voltages and currents. The discrete wavelet transform (DWT) is used for the fault feature extraction corresponding to band frequency 12.5- 6.25 kHz and therefore localizing this fault occurrence. The detection security is enhanced...
Power system asset management is balancing between multiple attributes and it deals with the question of a comprehensive long-term optimized solution for the desired service target. This paper concentrates on investment planning using a portfolio tool where probabilistic methods are applied to aid decision-making. The main aim is to outline a specification for such a tool. In addition to capital,...
