Auto‐reclosing scheme with adaptive dead time control for extra‐high‐voltage transmission line [PDF]
IET Science, Measurement & Technology, 2018 Discrimination between transient fault and permanent fault is contemporary problems for protection of transmission line. Auto‐reclosure is one of the foremost solutions for the same. This study presents the development of auto‐reclosure scheme using modified full‐cycle discrete Fourier transform with adaptive dead time control.

Adaptive Single Phase Auto-Reclosing Using Voltage Magnitude Pattern
, 2020 This paper presents a novel adaptive single phase auto-reclosing (ASPAR) scheme based on the first derivation of local voltage magnitude (VM) of the faulted phase for determination of dead time of transient faults. The algorithm is fast and uses low-frequency sampling and adaptive threshold value (ATV).

New approach to adaptive single pole auto-reclosing of power transmission lines
IET Generation, Transmission & Distribution, 2010 In this study, a novel digital algorithm is introduced for recognition of arcing (transient) faults and determination of dead time for adaptive auto-reclosing. The algorithm distinguishes between arcing and permanent faults by using the zero sequence voltage measured at the relaying point.

Development of a novel single-phase auto-reclosing scheme for distribution network with integrated distributed generation. [PDF]
, 2010 According to G59 recommendation, the common practice adopted by utilities in the UK is to disconnect Distributed generators (DGs) immediately once a network fault is detected to prevent islanding operation and disruption of the operation of conventional ...

Effect of duration of the pause single-phase auto-reclosing on electro-power transmission capacitance [PDF]
, 2017 This paper discusses the problem associated with accidents in the aerial line (AL) ultra-high voltage (UHV) due to its big length. In lines with a voltage of 500-1150 kV the overwhelming proportion of trips (98%) is caused by single-phase short circuit ...

Modular Hybrid DC Breaker-based Adaptive Auto-Reclosing Method for MMC-HVDC Systems
2020 22nd European Conference on Power Electronics and Applications (EPE'20 ECCE Europe), 2020 In this paper, the modular hybrid DC breaker is employed to inject active pulses after fault-current interruption and arc extinction due to a pole-to-pole fault in MMC-HVDC systems with half-bridge submodules. The power electronic branch of hybrid DC breaker is made of $n$ series modules, which allows generating active pulses with a controllable ...

A novel approach to adaptive single phase auto-reclosing scheme for EHV transmission lines
International Journal of Electrical Power & Energy Systems, 2011 Abstract In modern interconnected power systems, nearly 80% of faults in high voltage transmission lines are intrinsically transient. The necessity of rapid fault clearing has resulted in fast development of protection equipments. Moreover, need for reliable supply of loads has led to improvements in single phase auto-reclosing equipments.

Permanent Fault Identification Scheme for Distribution Feeders Using Detection‐Based Reclosing
IET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.This paper proposes a novel permanent fault identification scheme based on detection‐based reclosing to mitigate the risks of blind three‐phase reclosing and overcome the sensitivity limitations of existing methods. ABSTRACT To mitigate secondary damage caused by reclosing a distribution line with a permanent fault, a highly sensitive fault property ...
