It is very important that VFDs are installed correctly in order to minimize interference to other equipment.
There are a number of basic rules that should be applied to the installation procedure to minimize problems and these are usually covered in the instruction manual for the VFD.

I have recently come across a number of VFD installations that are causing severe interference with flow meters and other equipment to the extent that some equipment has been damaged by the induced noise levels.

I am looking for a simple test and/or equipment that can be used by an installer to see if the VFD installation is satisfactory. This does not need to be a full compliance test, but just a reasonable indicator that the installation is not "BAD", and that it is safe to install sensitive equipment near by.

Any one got any experience or suggestions?

Best regards,
