“…Several field measurements were done to prove whether the reduced short extinction times could be reached in reality. In most cases, these tests confirmed the expectations regarding the extinction time [12,13,15,16]. This is not only because the secondary arc RMS value is that low, but because the rate of rise of the recovery voltage is significantly smaller compared to single-phase interruption on uncompensated lines [12,15].…”

“…In most cases, these tests confirmed the expectations regarding the extinction time [12,13,15,16]. This is not only because the secondary arc RMS value is that low, but because the rate of rise of the recovery voltage is significantly smaller compared to single-phase interruption on uncompensated lines [12,15]. Further on, the field test in [16] shows that for very short extinction times not only the AC component of the secondary arc can prolong the extinction time.…”

“…A secondary arc current prolongs the extinction time of the secondary arc and needs to be considered for the dead time. If this current does not exceed a certain value, the fault arc may extinguishes and the system can be restored to normal operation [10][11][12][13][14][15][16]. Collected results from laboratory and field test for various voltage levels according to [9] Two different types of extinction phenomena were observed, the instantaneous break-off and the steady extinction.…”

An approach for a real time adaption of the dead time for auto-reclosing on high voltage lines was proposed. The objective was the optimal adaption of the dead time of a currently running single-phase auto-reclosing cycle by calculating the secondary arc current based on measurements. The algorithms for optimization were performed for real time application. For this purpose, the fault location plus the load currents of the parallel non-faulty conductors were measured. The measurement and the calculation of the dead time took place during the fault and the dead time period. In this way, an optimized dead time setting with regard to the actual fault location and loading conditions were achieved. This approach results to an on-line determination of a minimum necessary dead time of a successful reclosing under consideration of the fault location and prevailing loading conditions. Analytical calculations and numerical examples as well as high voltage field tests verified the results.

“…Three phase faults of HV transmission lines are quite rare and when they are happening most probably they will not be removed by auto-reclosing. Thus single-pole auto-reclosing [7]- [12] has become an increasingly more viable approach to the operation of HV systems in recent years. Indeed, successful single-pole autoreclosing represents a significant step in improving system performance and is an attractive, economical means of obtaining acceptable transient stability with fewer lines [13].…”

In this paper a novel method of ATP (Alternative Transients Program) simulation for single-pole auto-reclosing is introduced. This paper presents an investigation of single-pole auto-reclosing on HV transmission lines. By simulating real trapped charge, overvoltage profile is monitored. Most of the faults on HV transmission lines are single-pole to ground. In order to have a general overview of single-pole auto-reclosing and calculating overvoltages simulation should be performed. Using ATP software, single-pole auto-reclosing on two real 400 kV transmission lines is simulated and the results are discussed. Details of system modeling are outlined. The simulation method and modeling of a real single-pole auto-reclosing by ATP is presented in detail. Effects of transmission line length as well as number of circuits are analyzed. Effects of reclosing time on single-pole switching overvoltages are outlined. Differences between single-pole auto-reclosing at different phases due to position of conductors are also presented.
