Example of CDN
For screened cables, other CDN structures are used: no capacitors are needed for disturbances injection (see CDN for unscreened cables) since intrinsic capacitor of the screened cable (dot lines) is used.
CDN_S1 for screened cables In the case of X screened conductors, the CDN_Sx scheme is identical, but involves X conductors. R=100 Ohm; L> 280microH at 150kHz.
