Development and Performance Analysis of the Rogowski coil sensor for Arcing Fault Measurement

Abstract

Arcing fault is an overvoltage that usually occurs in the power system network, and it is necessary to monitor this phenomenon in electrical equipment. This paper presents the Rogowski coil (RC) as an arcing fault sensor. Finite element method (FEM) software used for analysing the RC magnetic flux density with two types of RC with the different turns and size demonstrated. The sizing of RC based on the 240 mm2 cross-link polyethene (XLPE) 11 kV underground cable. The prototypes of the RC sensors were designed using Solidworks software and three-dimensional (3D) printer for fabrication purposes. The main objective of the experiment is to investigate the RC effect with high magnetic flux density by implementing in real measurement. An experimental setup for real arcing fault with various voltages (up to 15 kV) was conducted to verify the RC performance, such as sensitivity and bandwidth range. The result has shown that the bandwidth of RC 1 is higher than RC 2 in all measurement by 22.6%.

Design and applications of Rogowski coil sensors for power system measurements: A review

“…To cope with the above mentioned issues, additive manufacturing (3D printing) offers excellent capability of maintaining the geometric structuring such as core symmetry of the winding, central position of the primary conductor, and its orthogonal position to the surface defined by the coil itself [55]- [56]. In addition, before the real construction using 3D manufacturing begins, the simulation and design tools such as Finite element method (FEM) and solid works are also being used to analyze the electromagnetic and geometrical properties of the coil [57].…”
