Webinar: Shielding/Grounding Best Practices for VFD Applications

Revere and LUTZE cover some best practices when using VFD specific cable. This on-demand webinar covers:
- Other components in a VFD system that can improve performance
- Why VFD specific cable is important
- Impacts of Grounding and Bonding on a VFD System
- How To’s on: EMC Fitting Installation, Grounding Pigtail Creation, and use of VFD cable at a local disconnect

very good information

That is a bad practice to add a pigtail to any shielded cable, this is not as effective as a direct 360° clamp, Pigtails in general can be a source of noise, there are many Shield clamps available even custom made to suit the application

[@revereelectric]

We agree that 360 degree fittings/clamps are the best practice solution, and we even acknowledge them in the webinar at multiple points (the EMC Fitting at the motor junction box, the fixed Shield Clamp on EMC rail, and the Spring Shield Clamp on the same rail). Our intention with showing how to make a pigtail was to demonstrate the most effective way to utilize one, as the difference between a well-made pigtail and a poorly made one can be significant. This way when the decision is made to utilize a pigtail rather than a shield clamp of some kind, the noise issues can be held to a minimum. But you are correct, a 360 degree termination of the shield will always be the most effective method for mitigating noise.
Please let your Revere Electric Account Manager know if you’d like to further this discussion, or send us a note for more information on this subject.

@@revereelectric Still no excuse for the use of Pig Tails for Shield Grounding just ends with a bad result, the video started off very well until the Pig Tails
