“…Mousavi There have been studies in the past for detection of incipient faults on some of the assets [1]- [5]. There have also been studies that focused on determining the symptom parameters that may be positively correlated with the failure and that could be used to form a heuristic algorithm for predictive maintenance [6].…”

“…This paper focuses on a unique class of incipient faults in underground cables that results from moisture/water intrusion and subsequent intermittent self-clearing arcing in splices [5]. The fault clears itself very fast by the vapor pressure, preventing any protection device operation and thus earning the self-clearing title.…”

This paper deals with the subject of incipient faults in underground distribution systems and their progression over time leading to an eventual permanent failure. Field data recorded from an underground distribution feeder were analyzed in both time and frequency domain to identify the symptom parameters and characterize the observed incipient behavior. This exploratory data analysis sheds additional light on the progressive characteristics and nature of these self-clearing faults and advances the fundamental knowledge in an effort to detect such pre-mature failures before developing into a full-blown fault.Index Terms-Distribution system, underground cable, incipient fault, splice failure.

“…Relatively common sub-cycle faults, whose observable signal change is shorter than one cycle [24]- [26], are not easily handled using conventional fault location methods. The IEEE Standard C37.114 TM Section 6.10 [27] states that travelingwave approaches may be the only solutions for short-duration faults.…”

Single-phase-to-ground sub-cycle faults in the distribution network can be located using voltage sag fault location. This paper illustrates how a sensitivity study of measurement imperfections can be used to quantify the impact of sub-cycle faults on voltage sag based fault location. Our results suggest that there is a complex relationship between factors influencing error in fault location because the design of the study covered a wide range of conditions. The more complicated, higher order interactions have a stronger influence on error than any particular input factor alone.

Matrix Pencil Method (MPM) has been applied to sub-cycle information of space vector and zero-sequence voltage to classify voltage dip phenomena. The feature extraction performance of MPM using different sampling window width has been statistically analyzed and found to perform relatively well between 0.1 and 1 cycle of a damped complex sinusoidal signal. The results show that MPM is able to estimate the fundamental frequency space vector even in highly distorted signals. The space vector ellipse's estimation is further enhanced by augmenting an ellipse fitting algorithm to MPM. This enhanced method differentiated between two highly similar two-phase voltage dips using only a quarter-cycle of data, demonstrating the feasibility of this scheme. This is demonstrated in a fault simulation on IEEE 34-bus system using a 5 ms sampling window.
