在三相合成测试电路中，触发真空间隙（TVG）用作快速开关。为了对该试验电路中重燃装置的六个电容器组（50 kV，12.5 kJ）放电，密封TVG与玻璃陶瓷表面触发器一起使用。为了在电压注入装置的每相接通低振荡电流，三个连续泵送的TVG与聚缩醛蒸发触发器一起使用。由于10 mT/kA的自生轴向磁场，该TVG也能够在前4 ms期间切换14 kA rms（50 Hz）的高电流。自1982年以来，两种类型的TVG在KEMA高功率实验室的145 kV、50 kA三相合成测试电路中运行。
In a three-phase synthetic test circuit triggered vacuum gaps (TVG's) are applied as fast switches. To discharge the six capacitor banks (50 kV, 12.5 kJ) of the reignition installation in that test circuit, sealed-off TVG's are used with a glass-ceramic surface trigger. To switch on a low oscillating current in each phase of the voltage injection installation, three continuously pumped TVG's are used with a polyacetal evaporating trigger. Because of a selfgenerated axial magnetic field of 10 mT/kA this TVG is also capable of switching a high current of 14 kA rms (50 Hz) during the first 4 ms. Since 1982 both types of TVG's are operational in a 145 kV, 50 kA three-phase synthetic test circuit at KEMA High Power Laboratories.
