“…6, the current will be zero, the arc will extinguish, and the arc voltage will quickly be equal to the driving voltage again. If the driving voltage at this point is equal or larger than the arc re-strikes immediately and the current wave becomes sinusoidal, so amplitude and shape of the arc current become identical to those of the short-circuit current [23]. But if it is below ers, the arc will not re-strike.…”

For maintaining security of distance relays, power swing blocking is necessary to prevent unintended operation under power swings. To be dependable, distance relays must operate whenever a fault occurs. Therefore, detecting faults during power swings is an important issue since the relay should be able to differentiate the fault condition and not be blocked during that time. This paper presents a new method for detecting a symmetrical fault during a power swing, based on extracting components of the current waveform using the Prony method. The merit of the method is demonstrated by simulating different faults during power swing conditions using the Alternate Transients Program version of the Electromagnetic Transients Program.Index Terms-Distance relay, power swing, prony method, symmetrical fault.

“…However, there is no clear explanation why arcs tend to reignite in roughly the same polarity [15,16]. These faults contain a conducting state during which current flows through the arc and a nonconducting state without any arc.…”

SUMMARY Impedance‐based fault location methods to date are able to locate only permanent and linear faults. Current fault location methods assume that arc resistance is constant to locate the fault. However, because of the variable nature of the arc resistance, arcing faults cannot be considered as a linear fault. Furthermore, the duration of intermittent and transitory faults is not necessarily enough for fundamental frequency‐based fault location methods. Therefore, available methods are not applicable for arcing fault location. In this article, a novel method is proposed for arcing fault location using time‐based formulation. The advantages of the proposed method over available methods are as follows: (i) fewer samples are necessary for the algorithm to calculate the location, (ii) it is capable of locating variable resistance faults, and (iii) it is independent of arcing fault type. The validity of the devised algorithm is studied within the power system computer aided design‐electromagnetic DC (PSCAD‐EMTDC) environment. Two different arc models have been simulated, and the produced data have been used for fault location algorithm. The results show a good accuracy for both arcing fault models.
