点検装置。 When the power supply voltage drops instantaneously, the energy stored in the capacitor corresponding to the amount of voltage drop is injected into the power supply circuit connected to the load via the transformer as a compensation voltage. A disconnection switch is provided on the input side to the capacitor and the output side from the capacitor by a wire, and a voltage dividing resistor is connected between the terminals of the capacitor to divide the voltage and serve as a reference, and a voltage dividing resistor is connected in parallel to the voltage dividing resistor. A discharge switch and a discharge resistor are connected in series, the initial value applied to the voltage dividing resistor at the time of charging is inputted to a hold circuit, and the voltage held by the hold circuit and the voltage applied to the discharge resistor are compared in a comparator. A capacitor capacity inspection device for an instantaneous voltage drop compensator, characterized in that the pass/fail of a capacitor is determined based on the time from when the discharge switch is turned on until the voltage applied to the voltage dividing resistor matches the voltage applied to the discharge resistor.
