A load testing apparatus includes a resistive unit that includes resistor groups having a plurality of resistors and is connected with a power source to be tested for a load test. A cooling fan that cools the resistors in the resistive unit is provided. A control unit is provided. The resistive unit is provided with a current/voltage detection part that detects a current flowing through the resistors and a temperature detection part that detects an exhaust temperature at a downstream of the resistive unit. A rotation state detection part that detects a rotation state of the cooling fan is provided in the cooling fan. The control unit performs off control that stops power supply from the power source to be tested to the resistive unit based on information from the current/voltage detection part, information from the temperature detection part, and information from the rotation state detection part. |
