| Abstract: | By analyzing the resonant over-voltage in 10 kV power supply system with its neutral point being unearthed, illustrates the conditions causing the resonance over-voltage and their types and characteristics, and puts forward the following measures to suppressing resonant over-voltage: by adopting automatic tuned earthing compensation device or silicon-controlled resonance suppressor, connecting the arc-extinguishing coil with neutral point of the voltage transformer or connecting the resonance suppressor. |
