Trigger Transformers for Three-Electrode

Our trigger transformers are used to provide a fast high voltage pulse. This high voltage pulse is applied to the third (trigger) electrode to initiate switching action in the three-electrode spark gaps.

Our standard range of trigger transformers are designed to provide fast rise-time pulses, typically up to 30kV/µs, for triggering three-electrode spark gaps.

Four types of trigger transformer are available, each with its own selective features. Either positive or negative pulses can be obtained from all of the transformers depending on how the primary winding is connected.
