    Inrush Currents Introduction Inrush Currents can be captured by Fluke 434. Inrush Currents are surge currents that occur when a large, or low-impedance load comes on line. Normally the current will stabilize after some time when the load has reached normal working condition. For example the start-up current in induction motors can be ten times the normal working current.
