Means for measuring control of impulsive overvoltage caused by thunderstorms

Abstract

The analysis of national normative and technical requirements of the lightning protection systems shows the necessity of additional protecting measures from the direct strike of lightning or voltage induction by a remote discharge by determining protective devices choice and charts of their settings. The protection of information and communication systems and their electronic devices components is particularly dependent on the thunderstorms in the environment. Methods of calculation and protecting schemes from impulsive overvoltage recommended by international standards of IEC, are more hard and reliable. Therefore, it is proposed to apply in the circuits of protection against impulse overvoltage means of measurements. The proposed means for measuring control detects and fixes impulse deviations from sinusoidal form of network voltage. On this basis the application schemes of control devices for impulsive overvoltage are complemented, that substantially reduces the risk of fires and electronic device damage from thunderstorm origin. Implementation in the field of operation and maintenance of electronic and telecommunication equipment is proposed.
