WebApr 17, 2003 · If the transmitting-location ground carries a noise signal different from that at the receiving location, grounding the shield at both ends causes current flow along the shield. Grounding at both ends is acceptable if there is no substantial potential difference between the two ground locations. WebGrounding with Zener Barriers Bulletin 937 grounding is made simple by an integrated IS ground connection in the base of each barrier. By simply connecting each barrier to a standard 35 mm DIN rail, the total system can be grounded via a single point.

http://beta-a2.com/noise_grnd.html WebDec 30, 2008 · It provides numerous parallel grounding paths and thus avoids resonance situation. Resonance happens when the length of a ground lead coincides with quarter wavelength of the noise frequency (or 3/4, 1 1/4, etc.) causing the earth lead to act as an open circuit to these frequencies. With multiple ground paths, this is unlikely to happen.
