Abstract

PURPOSE:To achieve leakage current and polarity detection in a short time, by measuring the difference between transient currents flowing to a reference capacitor connected in series with a resistor and a capacitor to be measured which are designed for equal time constant. CONSTITUTION:Time constants consisting of a resistor 17 having a low impedance negligible in comparison with a capacitor 6 corresponding to an equivalent resistor 16 generating the leakage current of a capacitor 13 to be measured for the leakage current, a resistor 10 and the reference capacitor 6 connected to a one end of a DC power supply 9 and those consisting of a capacitor 13 and a resistor 15 are set equal to each other. When a switch 8 is closed and a voltage corresponding to the difference between transient currents flowing to the capacitors 6, 13 connected to one end of the power supply 9 is measured at a voltmeter connected between other ends of the capacitors 6, 13, the capacitor leakage current can be detected in a short time. On the other hand, since the transient current changes for tantalum capacitors depending on the polarity, the polarity detection can similarly be made in a short time.
