Abstract: The classification of grounding mode for 10kV power distribution network was introduced. The advantages of neutral point grounding by resistor were put forward. The advantages and disadvantages of higher, medium and lower resistance of resistor used in neutral point grounding were compared. It was pointed out finally that the neutralpoint grounding of 10kV power distribution network by resistor is helpful for elimination faults of power network rapidly and effectively.

Key words: 10kV power distribution network, neutral point grounding, resistance
