Temperature is an important factor for the service life of cable insulation. To ensure safety, the operating temperature of cables must be monitored. Since optical fiber temperature measurement technology is difficult to be used widely in medium volt

DC voltage is one of the important parameters of active power filters. Since the series hybrid active power filter does not withstand the fundamental voltage, it cannot absorb energy from the power grid, making it too difficult to control its DC volt

The transmission line maintenance is usually carried out by live-line maintenance, and equipotential live-line maintenance is one of the primary forms. In this process, the linemen need to enter the high potential with the help of conductive gloves o

Long air gaps are the main external insulation medium of overhead transmission lines. When there are floating conductors in the air gap, the gap’s configuration changes, and the combined air gaps is formed. We built an experimental platform to obta

Due to space limitations of transmission corridors, ultrahigh voltage (UHV) lines inevitably cross over other lines. UHV lines in a crossover section have a lightning shielding effect similar to that of a lightning conductor of lower lines. While, wh

Abstract In this paper, four novel kinds of triazine-trione based tri-imidazole derivatives (IM-TT, 2MI-TT, 2EI-TT and EMI-TT) were synthesized through the addition reaction between triglycidyl isocyanurate (TGIC) and imidazole (IM), 2-methylimidazol
