Abstract: A high voltage impedance device with surface leakage proof configuration is applied in a divider. Aforementioned divider is assembled by a high impedance element, an inner case body and an outer case body. The high impedance element is sealed in the inner case body and a closed interlayer between the inner case body and the outer case body is filled with noble gas as an insulating layer. While the high impedance element is applied in high voltage, the closed interlayer can prevent the current-leakage from forming impedance paralleled with the high impedance element. The current-leakage is formed on the surface of insulting portion, or is formed by moisture, dust or corona effect. Therefore, the current-leakage proof divider may maintain the stability/linearity of the voltage division and then reduce the distance between two ends of the high impedance element effectively and still maintain the linearity of measuring voltage.
