to save the motivation i advice you to change the line of work for a
while - from the practical to the theoretical one :-)

you may model this situation in the program "bela" - "finite element
electrostatics solver". i`ve downloaded it recently, approximately
after a hour i learned how to work with it - it`s very simple. the
only problem - its viewer works very slowly on my athlon xp 1600+, i
tried pentium IV 3GHz with dual DDR on 400 MHz - almost the same.
maybe because at the moment i have 541790 nodes and 1083447 elements,
maybe not - Antonio`s "inca" draws the field plot very slowly too,
even with several orders lesser elements number.

but - it`s a funny time-spending, you`ll forget all your current
problems :-)))
the program doesn`t have such thing as "voltage profile", but it`s not
a problem - i`ve defined 220 wires manually with the 500v (as it would
be in my real secondary) step - these are 220 turns of the secondary
in the place i was interested. nothing difficult - a couple albums of
good drum`n`bass music and that`s it :-D

the very first result is the following:

there`s a small built-in dielectrics base in the program, plus you can
explore the influence of different shields beetween the windings - i`m
only beginning to work with that now.
classical flat primary is too simple and too boring to - isn`t it? ;-)
