A gas-insulated gap switch with an unusually high standoff-to-trigger voltage ratio is described. Designed to standoff 500 kV when pressurized with SF/sub 6/ at 1.5 MPa (212 psi), the switch was triggered with as little as 19.3 kV across the gap by firing a shaped charge from one electrode toward the opposite electrode. Similar air-insulated and SF/sub 6/-insulated gaps pressurized to 83 kPa (12 psi) and designed to standoff 50 and 150 kV, respectively, were triggered with 15.4 kV across the gap by firing an ordinary RP-2 detonator from one electrode toward the other.
