Title: Calibration method of standard potential divider
Inventor: SAKAMOTO YASUHIKO
IPC: G01R35/00
Filed: 2001-07-10
Abstract: PROBLEM TO BE SOLVED: To solve the problem that a method for evaluating the magnitude of a leakage current and correcting its influence is required, in the background of such a problem that insulation between a reference voltage source and the ground becomes difficult to be kept sufficiently high when the rated voltage of a standard potential divider is raised, to thereby generate leakage of a current from the reference voltage source to the ground. SOLUTION: One pair of terminals of the standard potential divider and a floating reference voltage source is short-circuited, and a voltmeter is connected between the other pair thereof, as shown in figure 1 (a) or (b). A voltmeter having high input impedance can be used as the voltmeter, and difference voltage measurement can be performed by two kinds of connections as shown in figure 1 (a) and (b). When using the voltmeter having the high input impedance, a leakage current 3 flowing by imperfect insulation between the floating reference voltage source and the ground flows through the short circuit from the standard potential divider. In this case, the voltmeter indicates differently between the case (a) and the case (b), because the terminals of the standard potential divider from which the current flows are different between both cases.  Circuit analysis thereof is performed to execute correction.
