Development of new ways of designing of HV-insulation for power energetic with improved reliability on a basis of newest knowledge about surface discharge
The modern design of outdoor HV insulators is determined by rules that follow from characteristics of mechanisms of their flashover, such as: 1) The leader-streamer mechanism of breakdown of gaseous gaps close to dielectric surface under impulses of over voltages; 2) The mechanism of flashover of insulator on an AC by partial arcs with polluted and humidified surface. As a result of our research, [1-5], a new alternative mechanism of flashover of HV insulation was discovered and investigated. The mechanism was named - anomalous discharge (AD). As it was discovered, AD-mechanism has essential practical value because it's capable to generate full flashovers on majority of modern insulators at much smaller voltages than it was considered earlier, (lightning and switching over voltages and also on AC). This research is devoted to the efficiency of non-standard ways for control of AD with purpose to increase reliability of work of power energetic objects as a whole, i.e. increase the real BIL of their insulation.
