Electric field characteristics of UHV DC tension string during insulator replacement by two workers

open access: yesIET Science, Measurement & Technology, 2022
The UHV DC tension insulator strings are often large‐tonnage suspension porcelain or glass insulators with high mechanical strength. The single insulator is heavy, so two workers working at the same time are required to make a replacement on insulator ...

Computation of Electric Field on High Voltage Polymeric Insulators Using Actual Model With Optimal Corona Ring Dimensions

open access: yesEnergy Science &Engineering, Volume 13, Issue 9, Page 4515-4538, September 2025.
Combination of four cases (few water drops, more water drops, different sizes of water drops (16.8 μL and 56.5 μL), and clean insulator) with the use of corona ring (140‐40‐90). ABSTRACT This article deals with the calculations of the electric field and the potential distribution of the polymer insulators of the HVTLs with the use of corona rings.
