Laser triggered air gap for applications in the field of power system

Due to its low jitter, good repeatability and controllable delay, laser triggered discharge has been used widely in the large-scale pulsed power machines to synchronize the discharge of multiply modules. Recently, for the applications in the field of power system, such as generating the precise currents by synthetic test circuit for the testing of high voltage circuit interrupters, experiments on the laser triggering DC high voltage gap in open air have been carried out.
