[pdf] Strip the insulation close to the motor cable ends. Plug the shielding of the cable into the. Low-frequency cable shield grounding At low frequencies the primary purpose of a shielded cable is to prevent electric-field coupling from 50/60 Hz power lines. No practical shield provides magnetic-field protection at low frequency. For low frequencies, shielded twisted pair is often used: the. Electromagnetic interference (EMI) is one of the biggest challenges in modern electrical and instrumentation systems. This whitepaper underscores that precise calibration of high-voltage test gear — especially when measuring 1 kV–150 kV systems —. To ground shielded cabl e, bond the shield to a low-impedance grounding path based on signal type and EMI risk.
