Hi Gary,

For a diode, the 1N4007 is rated at 1000V. However, you have to
design with Peak voltage in mind, and then add 50% safety factor for
good design. Further, feeding a capacitive filter requires you DOUBLE
the PIV rating. All in all, this suggests your design choice should
tend toward the divider before the detector. Then the question
becomes, do you want a peak reading meter, or an averaging meter? A
peak reading detector (AKA Clamp) will lightly load the divider
whereas the averaging will load it more (and ruin any fixed divider
ratio - which returns us to the variable component to be designed in).
