In an overvoltage detection device that distinguishes and detects whether the voltage increase on the DC feeding power line is due to a reduction in the train load or due to an abnormality in the voltage regulator, the DC overvoltage detection device operates when the voltage on the feeding power line exceeds a set value. An overvoltage detection device characterized in that an overvoltage relay, a contact that operates when a train load is present, and a time relay are connected in series, and an abnormality in a voltage regulator is detected by the operation of the time relay.
