Why Use A Ground Isolation Transformer?
Ground loops occur when there is more than one ground connection path between two pieces of equipment, and the duplicate ground path can pick up interference from the other ground wiring. Because of the interference from ground loop voltages, voltage potential becomes unstable and equipment can produce humming noises and harmonic unbalance. Computer systems operating on AC power that are networked to each by ground wiring throughout a building can often experience inter-system ground noise and interference. This causes a potential for loss of information and damage to equipment. Ground loops also occur in video systems when some components in the same system receive power from different grounds that dont have the same voltage potential. Since most computer networks, audio and video systems and other delicate machinery such as hospital equipment all use voltage sensitive devices, ground isolation transformers are used not only for the safety of the operators, but for the safety of patro
