摘要
The invention pertains to testing technique and designed to be used in the research n the dielectric rigidity of high-voltage equipment gaseous isolation. The technical result of the invention is the achievement of gas dielectric breakdown with relatively low voltage. A corona discharge is generated by supplying the initial voltage to the electrodes, defining the discharge gap so as to ensure a three dimensional load at the corona-producing electrode. Then, the total voltage, sufficient for complete breakdown, is supplied to the discharge gap with the uniformly distributed three-dimensional load and the breakdown of a gaseous dielectric takes place. The present method provides the decrease of corona discharge and formation of impulse pedestal with the help of additional dynamic discharger in the circuit, which electrodes are switched from the closed state to the open one.
