The roles for "impulse breakdown voltage" and the "DC breakdown voltage" in gas discharge tubes in SPDs?
Jul 30 , 2026
This is determined by the physical characteristics of the GDT and its different roles in the circuit. Impulse breakdown voltage (e.g., for a rise rate of 1 kV/μs): This parameter characterizes the response speed of the GDT to fast transient overvoltages. Standards require high stability (low dispersion) because GDTs are often used as primary protection and need to operate quickly and predictably t...
