Best Practices for High Frequency Grounding with AEGIS®HFGS (High-Frequency Ground Straps)
AEGIS®High-Frequency Ground Strap Ensures Reliable Bond Between Motor Frame and System Ground
- Reliable-low impedance path to ground for high-frequency currents from the motor frame to drive/facility ground.
- Improve the grounding system of VFD driven systems plus any attached or coupled equipment.
- Focus on NEMA and IEC frame motors for off-the-shelf selection in 12” and 24” lengths
- Custom engineered high-frequency ground straps for longer lengths.
What can cause Impendence to High Frequency Currents?
Note: Impedance is the “resistance” to high frequencies
- Long electrical wire lengths used in electrical connections can have a significant impedance to the high frequency currents
- Paint, corrosion, dissimilar metals, and multiple connection points can create impedances between surfaces
- Unshielded wire can induce electrical EMI and RFI across wires especially when multiple unshielded wires are all running in the same conduit
