Lightning Protection of Overhead Distribution and Transmission Lines by Multi-Chamber Arresters and Insulators-Arresters of a Novel Design - (PPT)

摘要

Reported are results of development work on multi-chamber arresters and insulators-arresters of a new type, quenching impulse arcs without a follow power arc. The devices permit protection of overhead power lines rated at 10 to 220 kV and above against induced overvoltages and direct lightning strokes without using a shield wire. They can be used at grids with short-circuit currents as heavy as 30 kA.
