Hi Chuck,
            Relative potentials are all-pervasive here....

Voltage of inner turn of primary relative to bottom of secondary. The 
secondary won't be truly zero relative to ground either because there 
is always ground resistance plus earth strap impedance and the RF 
current is rather high (which develops considerable potential across 
any impedance it flows through).  

My two cents,
