Inrush Current Research

Inrush Current Research

Inrush Current Research

(OP)
Hello everyone.
I've been handed a research project by the company I work for and would love to either find web links to the following information, or, a few answers here or there.  So, here goes:

1) What causes inrush current?
2) How can inrush current be moderated?
3) What calculations are available for estimating inrush
   current in a product?
4) What is the average timespan of an inrush surge?

Again, thanks to everyone who can, or will, provide information, links, or answers to any of the following.

Sincerely,
Chris Burk
Product Support Engineer

RE: Inrush Current Research

Are we talking about motors or transformers?

RE: Inrush Current Research

or capacitors?

I'm not sure how helpful this will be, but the majority of the products we will be developing this report for are power supplies, solid state devices (w/o capacitors), and various other PLC networking and communication systems.
