Usually video isolation involves breaking the ground in transmission lines to eliminate the 60 Hz hum; when there are high voltage potentials involved (above 20 VDC) the VIT series isolation transformers are the devices to use. The dialectric withstanding voltage of the VIT series is over 500 VDC. There is no DC path between transformer windings, therefore accomplishing true isolation.
