WebJul 12, 2006 · However, a earthed screen prevents the coupling altogether by simply diverting the noise currents to earth. Braided screens with 85% to 95% coverage are usually adequate. Screen earth connections can affect CMRR. It may surprise you to learn that cable capacitances between each signal conductor and screen are typically mismatched … Webi) Where screened signal or data cables are used, care should be taken to limit the fault current from power systems flowing through the screens and cores of signal cables, or data cables, which are earthed. Additional conductors may be necessary, e.g. a by-pass equipotential bonding conductor for screen reinforcement; see Figure 1. WebDec 6, 2012 · As earthing the braid at only one end, is a common practice with data and control, doing such with power and lighting may help. As you rightly point out, the braid is in effect only there as a screen, not as a CPC or earthed armour. Reply to Deleted member 26818 OP 4 44ALLAN Dec 6, 2012 #8 Wade, tsbp reference library
