Partial Discharge Measurements in a High Voltage Gas Insulated Transmission Line Insulated with CO2
Energies, 2020 This paper uses practical experimentation to analyse the effect of replacing SF6 with pure CO2 in conventional gas insulated transmission line sections by studying partial discharge measurements taken with applied voltages up to 242 kV (rms). The results

A Review on Real-Size Epoxy Cast Resin Insulators for Compact High Voltage Direct Current Gas Insulated Switchgears (GIS) and Gas Insulated Transmission Lines (GIL)—Current Achievements and Envisaged Research and Development [PDF]
Energies, 2020 Due to the ever-increasing demand for electricity in the one hand and the environmental constraints to use clean energy on the other hand, the global production of energy from remote renewable sources, particularly from large hydropower plants and offshore wind farms and their connection to the grid are expected to grow significantly in the future ...

Nondestructive Measurement of Residual Stress on Epoxy Insulators Using Thermoelastic Method
High Voltage, EarlyView.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, EarlyView.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.
