Inrush 

Introduction 

Inrush Currents can be captured by the Analyzer. 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. Inrush is a ‘single shot’ mode that records current and voltage Trends after a 

current event (the trigger) has occurred. An event occurs when the current waveform 

exceeds adjustable limits. The display builds up from the right of the screen. Pretrigger 

information allows you to see what occurred in advance of the inrush.
