What Is a Voltage Generator?
The impulse voltage generator is mainly used for power equipment and other test products to carry out the lightning impulse voltage full wave, lightning impulse voltage cut-off wave and operating impulse voltage wave to test the insulation performance.
- The ratio of the output voltage amplitude V2m of the impulse voltage generator to the charging voltage V is called the generator efficiency , that is,
- = (V2m / nV) × 100%
- For lightning shock waves, is generally about 80%; for operational shock waves, is sometimes only 60%.
- The impulse voltage waveform parameters T1 (Tcr), T2 and generator efficiency are related to the circuit structure and parameters, and need to be adjusted and determined through actual debugging.
- For power transformers, etc. with windings
- Nominal voltage: ± 300kV-4800kV class voltage: ± 150kV-1200kV
- Capacitance: 0.325-1.0F Impact energy: 7.34-480 kJ
