Abstract

In this study, wavelet transform is applied for three phase to ground fault detection and classification which occur at different locations in a 765 kV, 50 Hz twelve phase transmission line. The information of distorted energy, approximate and high frequency detail coefficients included in a fault current signal is captured using wavelet transform. Faulted phase determination is also carried out using the proposed technique concurrently. The effectiveness of the proposed protection technique is validated for three phase to ground faults, and various values of fault type, fault inception time, fault resistance, and fault location. Test results show that the proposed technique effectively detects the three phase to ground fault and discriminates the faulty phase effectively.
