Triangular base lightning arrester is a lightning arrester with triangular base, which is usually used for lightning protection in power system.
The triangular base arrester makes use of the nonlinear characteristics of zinc oxide. Under normal working voltage, the resistance of the arrester is very large and the current is very small. When the overvoltage is applied, the resistance drops sharply, and the energy of the voltage is released to achieve the protection effect
