Abstract
A smart voltage dip simulator apparatus and method are configured to test a motor starter ride through circuit. The simulator apparatus includes a power supply, an output switch, a test switch, a test lamp, a time selector, and a programmable logic controller. The power supply provides an output voltage to the motor starter when an output switch is actuated. A test of the motor starter is executed and a duration of the test is controlled by a selected time setting. The controller includes code therein configured to apply a predetermined dip to reduce the applied input voltage to the power supply and to generate the output voltage applied to the motor starter for the selected duration of the test. A method is performed to operate the simulator.
