“…Other researcher improved the model by adding and air gap that helped achieve the reigniting phenomena observed on staged faults. [135] where two dc sources, VP and VN, connected in anti-parallel by means of two diodes are used to model the fault. During the positive half cycle, the current flows through the VP terminal and during the negative cycle through the VN terminal, and these voltage values are maintained constant during the simulations.…”

“…The high impedance ground fault model applied in simulation experiments was developed basing on research and considerations presented in [3,4,9] but some new features were also included into the model implementation. To obtain dynamic features of the ground fault nonlinear impedance the digital arc model described in [9] was adopted.…”

-Application of wavelet transform technique to high impedance arcing fault detection in distribution networks is presented. Phase displacement between discrete wavelet coefficients calculated for zero sequence voltage and current signals at natural network frequency is tracked. The developed wavelet based HIF detector has been tested with EMTP-ATP generated signals, proving better performance than traditionally used algorithms and methods. The protection method proposed is efficient, robust and may be used for HIF detection independently of the network neutral point grounding mode.Index Terms -protective relaying, wavelet transform, distribution networks, high impedance arcing faults, transient analysis.

“…The installation and maintenance cost is very high. Electrical methods [6] such as proportional relay algorithm, arc detection methods, Kalman filtering method [7], low order current harmonic method [8,9], but each method has its own drawback. The early work examined arc frequency relaying and high frequency current detection but is not successful.…”

Electrical power system consists of many different complex dynamic and interacting elements, which are always prone to disturbance or an electrical fault. Transmission lines are exposed to atmosphere, the faults due to transmission lines are about 50% as compared to different types of faults that occur in the power system. The faults on electrical power system transmission lines are supposed to be first detected and then be classified correctly and should be cleared in least fast as possible time. This paper describes a fault-detection technique of faults in high voltage transmission lines using the wavelet transform. The wavelet transform (WT) has been successfully applied in many fields. The technique is based on using the absolute sum value of coefficients in multi resolution signal decomposition (MSD) based on the discrete wavelet transform (DWT). A fault indicator and fault criteria are then used to detect the faults in the transmission line. Wavelet transform is best suited for fault detection and classification. This paper describes a new fault detection technique which involves capturing the current signals generated in a system under faults. The detection process is based on calculating the absolute sum of the wavelet transform detail coefficients for one period. Wavelet transform is used for the decomposition of signals and feature extraction.
