Positive dc corona inception on dielectric‐coated stranded conductors in air

A review on mechanism and application of functional coatings for overhead transmission lines

“…In recent years, researchers have proposed many anti-corona coatings, which are expected to solve the corona problem. There are mainly hydrophobic coatings (Xu and Li, 2013;Yi et al, 2016;Zhang et al, 2019), TiO 2 coatings (Bian et al, 2018;Xu et al, 2022), and high dielectric coatings (Megala and Sugumaran, 2019;Megala and Pugazhendhi Sugumaran, 2020).…”

“…Xu and Li (2013) directly coated a 22.82 mm diameter cylindrical steel rod with a 1 mm thick RTV coating, and the AC corona loss was only about 40% of that of the bare steel rod. Yi et al (2016) found that the DC corona inception voltage increases with the thickness of the RTV coating on the aluminum conductor steel reinforced (ACSR). Zhang et al (2019Zhang et al ( , 2022 applied a commercial superhydrophobic coating on ACSR, the SCA was 162.4 °.…”

E ‐field computation in 765 kV substation using CSM with reference to occupational exposure

“…The charge simulation method (CSM) is a preferred numerical method for open boundary problems as it does not involve discretisation of the solution region [14][15][16]. CSM was used to calculate the E-field in a 400 kV substation, which consists of two buses and transmission lines.…”

Design of an HV capacitor using the inherent advantage of charge simulation method and experimentations

“…From its inception [7], CSM has been used for many cases involving the e-field analysis and its applications [3]. The CSM, even in recent times, continues to find its use in the e-field analysis of tri-electrode system [8], composite insulators [9], overhead transmission systems [10,11] and HV substations [12]. The CSM is an integral equation technique of computing the electric fields.…”
