    [2] [5] The "8/20 μs" generator is designed for surge arrester testing, and produces a high-current surge into a low-impedance load. [2] On the other hand, modern electronic devices can be high and low-impedance loads simultaneously due to non-linear devices, protection circuits, and arcing in a dielectric breakdown.

    However, a direct lightning strike (such as on a radio tower antenna) will cause the shunt to arc and conduct the massive amount of electricity to ground, protecting transmitters and other equipment. Another older form of lightning arrester employs a simple narrow spark gap, over which an arc will jump when a high voltage is present.
