6600V has been converted into 100V or 200V of the domestic use with the transformer on the pillar as shown in left figure.   If the insulation of this transformer is bad, high voltage apears second side of the transformer. So, it is very dangerous. To prevent this, the electric wire on the second side of this transformer is grounded.   Because second side of this transformer is grounded, We gets an electric shock when we touch with the case of an electric product that leaked electricity.   It is the mechanism that leaks electricity and gets an electric shock with electric product.
