For an ungrounded neutral low voltage power system in mine, its insulance (r) , capacitance ( C ) and leakage resistance ( R ) to the ground are three important parameters in determining the zero sequence voltage. In this paper the law of variation of the zero sequence voltage versus r,C and R has been analyzed separately. It shows that these zero sequence voltages are three different circles. Finally, two examples of its application have been given.
