Abstract
An inspection device includes: a charging unit that performs charging of a capacitor; a discharging unit that performs discharging the capacitor; a current measurement unit that continuously measures current of the capacitor during the discharging; and an abnormality detection unit that detects an abnormality of the capacitor based on a regression line relating to a discharge characteristic, the regression line being derived from a logarithm of measured values of the current in a determination time range during the discharging and a logarithm of measurement timings of the current.
Claims7
An inspection device comprising:
- a charging unit that performs charging of a capacitor;
- a discharging unit that performs discharging the capacitor;
- a current measurement unit that continuously measures current of the capacitor during the discharging;
- and
- an abnormality detection unit that detects an abnormality of the capacitor based on a regression line relating to a discharge characteristic, the regression line being derived from a logarithm of measured values of the current in a determination time range during the discharging and a logarithm of measurement timings of the current.
An inspection method comprising the steps of:
- performing charging of a capacitor;
- performing discharging the capacitor;
- measuring current of the capacitor during the discharging in a continuous manner;
- and
- detecting an abnormality of the capacitor based on a regression line relating to a discharge characteristic, the regression line being derived from a logarithm of measured values of the current in a determination time range during the discharging and a logarithm of measurement timings of the current.
