Induction Motor especially the squirrel cage type of this motor plays important role in industry. According to the application type, this motor place against various stresses that are caused failure in the motor. The most common failure is related to the Stator winding. Among these failures are turn-to-turn, coil-to-coil and phase to phase faults. Flow the high current do to the induction resul...

The single-phase-to-ground (SPG) fault at the valve side of converter transformer is one most critical faults threatening operation bipolar half-bridge modular-multilevel-converter-based multi-terminal direct-current (HB-MMC MTDC) systems. Following a valve-side SPG fault, upper-arm submodule (SM) capacitors in faulty may suffer serious overvoltage, and grid-side currents experience no zero-cro...

Voltage sags are the most common power quality disturbance usually associated with power system faults, which can cause huge economic loss, making it the focus of emerging research. The proposed voltage sag detection technique for a single-line-to-ground (SLG) fault is presented using the PMU measurement data for improving the power quality. Various voltage sag detection techniques have been di...

The Sen Transformer (ST) provides an economical solution for power flow control and voltage regulation. However, fault analysis evaluation of the performance transmission protection system in presence a ST have not been investigated. Hence, short-circuit model using phase coordinate method is proposed this paper. Firstly, according to coupled-circuit model, nodal admittance matrix between sendi...
