CONDENSER LEAKAGE CURRENT MEASURING METHOD AND CONDENSER LEAKAGE CURRENT MEASURING APPARATUS

摘要

PURPOSE: A method and an apparatus for measuring a leakage current of a condenser are provided to measure the leakage current accurately by applying a DC voltage to the condenser. CONSTITUTION: A linear feeder(1), a separation supply unit(2), and a work receiving hole(4) are regularly formed in a circular transfer table(3). The work is successively transferred to a plurality of charging stages(6). A charging stage(10) before the measurement completely charges the main capacity of the work after charging the dielectric absorption factor inside the work. The overcharged charge is discharged through an insulation resistor while the work is transferred to a measurement stage(7). When the work reaches the measurement stage, the leakage current is measured.
