Nondestructive Measurement of Residual Stress on Epoxy Insulators Using Thermoelastic Method
High Voltage, Volume 11, Issue 1, Page 274-283, February 2026.ABSTRACT Residual stress is inevitable in epoxy insulators, which easily leads to small cracks and even insulation breakdown during the operation of gas‐insulated transmission line (GIL)/gas‐insulated switchgear (GIS). This study proposes a nondestructive method to measure the residual stress on epoxy insulators using thermoelastic effects.

High Voltage, Volume 11, Issue 1, Page 297-304, February 2026.ABSTRACT Many researchers are committed to improving the diagnosis accuracy and solving the few‐shot problem on circuit breakers (CBs). However, the research on the vibration transmission mechanism of the fault is insufficient, which makes it difficult to find the potential design defects of CBs through vibration.

Breakdown Voltage Using Bond Energy Calculation for CF3CHCl2/CO2 Mixture as Insulation Applied
JAREE (Journal on Advanced Research in Electrical Engineering), 2019 — Sulfur hexafluoride gas according to the Montreal Protocol and Kyoto protocol needs to be limited and gradually reduced because it causes global warming, the greenhouse effect and acid rain on the environment.
