Grounding of Neutral Point of 3-Phase System | Earthing | Electricity
The following points highlight the four main methods used for grounding the neutral point of 3-phase electrical system. The methods are: 1. Reactance Grounding 2. Arc Suppression Coil Grounding (Or Resonant Grounding) 3. Voltage Transformer Grounding 4. Grounding Transformer. Method # 1. Reactance Grounding: Reactance grounding means grounding through impedance which is highly inductive. For circuits between 3.3 kV [...]
