NONCONTACT VOLTAGE MEASURING APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a noncontact voltage measuring apparatus of which the parasitic capacitance does not substantially amount to an error factor of voltage computations.

SOLUTION: The noncontact voltage measuring apparatus has a voltage computing means for connecting a detection capacitance via a coupling capacitance to a core wire with an impressed voltage to be measured and measuring a voltage between terminals of the detection capacitance to compute the voltage to be measured. The noncontact voltage measuring apparatus is provided with a capacitance detecting means for measuring the detection capacitance including the parasitic capacitance.
