The breakdown field of the enhanced should be multiplied by a (up to values of 1.2) for better accuracy in cases where the field at the center conductor is highly enhanced. 

The "mean" field is just the peak applied voltage divided by the electrode gap.

In cases where the entire area is not stressed, use that area which exceeds 90% of the maximum stress.
