Abstract :
The paper reviews the need for overhead line switching equipment and its use in developing countries for the control of long radial feeders into remote districts. The requirements for pole-mounted equipment and relaying characteristics are discussed showing the need for sensitive earth fault discrimination, particularly to detect broken conductors in regions of high earth resistance. Designs of pole-mounted, autoreclosers are discussed. Sectionalising equipment is also reviewed in the context of fault management on spur lines.
