PROBLEM TO BE SOLVED: To provide a compact detection device of output currents and ground fault resistance capable of monitoring the insulation state of a DC power supply, and monitoring the state of currents to be output from the DC power supply.SOLUTION: The detection device of output currents and ground fault resistance includes: a current detection part 8 for detecting output currents from a high voltage power supply on the basis of a magnetic field generated on a current path 22; and a ground fault resistance detection part 2 for detecting an insulation state between the high voltage power supply and a ground. The current detection part 8 and the ground fault resistance detection part 2 are arranged at least in the same case housing or on the same circuit board, and provided with: a first connector 1 arranged in the case housing or on the circuit board, and connected to the high voltage power supply; and a second connector 13 to which the drive power of the current detection part 8 and the ground fault resistance detection part 2 is input. The current detection part 8 and the ground fault resistance detection part 2 are configured to output detection results to the outside, and to acquire control information from an external device via the second connector 13. |
