Vicon V235GLTA ground loop transformer
The V235GLTA Ground Loop Transformer is a passive
ground loop correction device for coaxial control systems
. It differentially nullifies the AC current that
can occur in the video cable shield as a result of differing voltage
potentials at each end of the shield.
The difference in potential can arise from bridging of two
power distribution systems supplying the camera and monitor
in which the level of electrical ground varies. The result is the
production of an AC current in the cable shield. See Figures
The V235GLTA, designed specifically for a coaxial control
system, protects and restores the video signal. Waveforms
showing the effect of this restoration are shown in Figure
