More Information
Summary:Provided is an insulation resistance monitoring device that enables measurement of insulation resistance using a mega tester without removing the insulation resistance monitoring device. The insulation resistance monitoring device (100) that monitors the insulation resistance of an object to be measured such as a motor (40) includes: a current detecting unit (10) that is connected between the power supply line and the ground line of the motor (40) and detects a current flowing through the insulation resistance of the motor 40; a voltage generating unit (20) connected between the power supply line and the ground line of the motor (40); and a switch (30) for opening and closing the connection path between the power supply line or the ground line of the motor (40) and the voltage generating unit (20), wherein the off resistance when the connection path is opened is 100 MΩ or more.
