Analysis and improvement of gas density relay anti-interference under the strong electromagnetic environment

Aiming at the grounding problems of gas density relay under strong electromagnetic envi- ronment, by concrete analyzing the reasons such as the space interference, the ground interference and the conduction interference, the effective improvement measures were put forward to avoid the fault of gas density relay. The application result shows that the improved gas density relay runs more stably and effectively to reduce the failure rate of the gas density relay, which provides reference for the design, hidden trouble treatment and technical transformation of the gas density relay grounding under strong electromagnetic environment for the later super or ultra high voltage project.
