The work presents experimental study results of gas discharge interrupter with a sector hole in the screen and a circular grid hole being asymmetrically placed regarding central axis as part of a high-voltage pulse generator with inductive energy storage. According to the results received the device under consideration managed to decrease minimum turn-off time by 6 times up to 30 ns compared to a switch with inverse hole pattern in a grid node. Limiting pulse voltage amplitude is fixed at the level of 50 kV, peak pulse power increase up to 13 MW is achieved.
