摘要：

The high-speed detection of fault-induced transients of an overhead three-phase transmission line is important to detect the fault, determine whether the fault is internal or external, and locate the fault. In this reported work, the wavelet coefficients of the maximal overlap discrete wavelet transform were used for real-time detection of fault-induced transients by means of the real-time digital simulator.
