Can do, A Float or Floating AC power distribution method system simply means ITS NOT GROUNDED. By the way GREAT QUESTION
For example, in your household 120/240 Volt Single Phase Three Wire system that uses just one transformer (perhaps say 7200 or 9600 etc VAC down to 240 VAC) the center of that transformer is tapped, serves as the Neutral, and that point is tied to a #4 Bare Coper Wire that leads down the pole to MOTHER EARTH GROUND. Its a Grounded NOT floating system. Likewise at the main service entrance the Neutral is again tied to a Grounding Electrode via the GroundING Electrode Conductor # 4 bare copper wire.
LIKEWISE In a typical say 208 Y 120 Volt Three Phase Four Wire commercial system, the common tie point where each of the three transformers are all joined together, ALSO SERVES AS NEUTRAL AND IS ALSO TIED TO MOTHER EARTH GROUND (perhaps via a driven into the earth rod or rods or perhaps other suitable Grounding Electrodes), A GROUNDED (NOT Floating) System.
HOWEVER and as used a lot in the thirties through 60's, if three transformers are connected in a Delta configuration (usually 240 or 480 line to line) and theres no connection to earth ground (or any Grounding Electrodes), THEN THAT SYSTEM IS FLOATING. NOTE Im talkin a 240 or 480 Three Phase THREEEEEEEEEEEE Wire here, not 3 phase FOUR wire where (Red/High Leg system) one transformer is center tapped and that point is tied to a grounding electerode.
So in theory if you ignored capacitive and inductive coupling you can be standing barefooted on the ground and touch any lead and not receive a shock since there shouldnt be any voltage with respect to mother earth ground in a floating system. Similar in a plant if one leg got shorted out to a machine or building steel or conduit etc the motor keeps running THATS A FLOATING SYSTEM
That help?? that what you were looking for??
Again GREAT QUESTIONS YALL Hope I helped and didnt confuse by use of my technical jargon, but thats sort of inbred after Purdue and 40 + years lol
