Composite Housed Transmission Line Arresters of High Voltage
Line Arresters:
Line arresters are an effective and economical option to protect
existing as well as new transmission lines against lightning
overvoltages in order to increase grid reliability and availability
of transmission lines. Line arresters are suitable especially for
line sections with low earthing impedance of the line towers, areas
with high lightning activity, transmission lines without shield
wire protection and for transmission lines with very high demand to
their availability.
