It has a good effect to debase anticipating touchvoltage.
它能在降低预期接触电压方面起到良好的效果。

The seasonal coefficient of grounding resistance possibly reaches 3.0 in freezing region of North China, and those of touchvoltage and step voltage 10 and 5.4, respectively.
The problems to be dealt with are also pointed out . Equipotential bonding is a very effective measure for reducing step voltage and touchvoltage and preventing from counter-attack.
