Jim,
Having just gone through the HV voltage divider design zoo with my
equipment, I have one caution. At 60Hz the long string of resistors will
work fine. However, if you wan't to measure voltage waveforms at say 200KHz
the frequency response will be bad. I am now persuing vacuum molded epoxy
encapsulation to get small size, reasonable power dissipation, and high
frequency response. Your oil bath should do the same just a little more
"fluid" :-) Do try to make it very compact.
