Steep waveform generator units are used to generate the steep wave front waveform. They comprises of one steep waveform generator gap unit and resistive voltage divider.
The gap unit consists of sphere gaps, transmission gear, capacitors and corona rings, which are mounted on the rectangular metal base.
Insulator type | Nominal voltage | Steepness | Front time | Standard | Response time |
Composite suspension and tension insulators | ≥1000V | ≥1000kV/μs | — | IEC62217 , IEC61109 | <35 ns |
Insulators of ceramic material or glass for overhead lines | ≥1000V | ≥2500kV/μs | 100-200ns | IEC61211 | <35 ns |
