I have designed a control system using Arduino and mu customer came up with the requirement for EMC compliance. I have just looked at the severity levels and I have to comply for 1kV level of Surge and EFT. How do I begin. Googling gives lot of options but not to the point. I need to protect only power lines , ie.. +5V from the Transient voltages. I seek expert advice

Sure it doesn't But you can get the parts from mouser, farnel ..., just use the search field.
