How do I calculate the ground impedance of VFD cable that has three ground wires? The cable consists of three conductors and three bare grounds wrapped in a copper tape shield. The grounds are in continuous contact with the copper shield.
Does the tape shield connect the bare grounds in parallel? If so, the resistance would be 1/3 of one ground, but I'm not sure it's that easy.
Thanks
