Grounding requirements: There must be a reliable grounding point, and the grounding resistance should be less than 1 to ensure the safe and stable operation of the system.
Main technical parameters:
Nominal lightning wave impulse voltage: EDHG-SGSC-200kV, which means that the standard lightning wave impulse voltage that the system can generate is 200kV.
Nominal capacity (energy): 10kJ, which means that the nominal energy output of the system is 10 kJ.
Level capacitance: 20 F, 50kV, means that the cascade capacitance value of the system is 20 microfarads, rated voltage of 50kV.
Level voltage: 50kV, which means that the rated voltage of each stage is 50kV.
Level capacity: 4 25kj, which means that the system consists of 4 levels, and the capacity of each stage is 25 kJ.
Output waveform: The standard lightning impulse full-wave voltage waveform that the system can generate under a load capacitance of 3500pf (including the voltage divider). Specific waveform parameters include wavehead time, wave tail time, and overshoot.
Synchronization range: greater than 20%, indicating that the synchronization operation range of the system exceeds 20%.
Duration of use: The system can work continuously at less than 80% of the rated working voltage; At operating voltages above 80%, the system should operate intermittently to avoid overheating or other damage.
Amplitude adjustment error: less than 1%, which means that the error of the system is controlled within 1% when adjusting the output voltage.
Minimum output voltage: not more than 10% of the nominal voltage of the equipment, that is, the minimum output voltage does not exceed 20kV.
