The elimination of a common ground connection that can cause circulating
currents in a signal conductor in the unbalanced circuit (in the screen)
because
in unbalanced working the screen is used as a signal conductor as well and
a
voltage will be added to the signal (of magnitude RDCscreen x Iground
loop).
That's a circulating current as in a loop hence ground loop.

The voltage added may actually be larger than that if poor internal
grounding
stategies have been used in the equipment under consideration due to RDC
of pcb
traces before the ground loop current finds it way to 'chassis earth' too.
