I say that your response is completely false and you are missing basic
electricity facts. The high voltage becomes an issue when insulation
breaks down, and then *current *starts
to flow through the fault path converting to emf & heat directly and via
induced current resulting ; P = E X I*. *Without the current the heat
does not occur, it is basic physics, and
the heat is directly proportional to the current. Voltage can exist
without current, but current cannot exist without voltage. Heat produced
is directly proportional to the current whether
it be in the intentional circuit path, or fault path caused by high
voltage insulation breakdown..
In addition, your statement that only current in the balun circuit can
produce heat is completely false. High voltage RF can create major
core heating due to dielectric losses in the ferrite core independent
of the magnitude of current flow in the tuning circuit. Several
discussions on the TowerTalk reflector have pointed this out over the
years for baluns and common mode chokes in ham radio applications.
