RE: oil dielectric

Hi Robert,

>A closed chamber of oil will expand in proportion to temprature. Simply use
a stand pipe connected with an elbow
from the base of your oil coil assembly. as the oil expands  it will rise in
the plastic stand pipe. you can mark the pipe like a thermometer and display
the _average temperature.

Excellent suggestion.  I may incorporate this at some time in the future to
see if there is any heating in an oil jacketed, air core secondary coil.
