Abstract
A voltage detection device is such that an intermediate electrode is provided between a central conductor to which a voltage is applied and a grounded tank to constitute a voltage divider and detects a voltage of the central conductor on the basis of a voltage of the voltage divider. The voltage detection device includes an integration circuit to which a voltage of the voltage divider, which is an output of the voltage divider, is input, an analog circuit that amplifies an output voltage of the integration circuit to a specified amplitude, an amplifier/attenuator to which a voltage of the voltage divider, which is an output of the voltage divider, is input and that amplifies or attenuates the voltage of the voltage divider to the specified amplitude, and an adder that adds an output voltage of the analog circuit and an output voltage of the amplifier/attenuator.
