I am aware of the potential problems of using long cables on the output of VFDs with the IGBT output switching causing a high voltage standing wave, stressing cable and motor insulation. Also problems caused by common mode noise from such systems.
Are the same problems likely with...
When doing calculations for voltage drop when motor starting, I have always used figures of 20% at motor terminals or 15% at the switchboards as maximum allowable.
Can anyone tell me if there is a British Standard that actually defines the allowable voltage drop and time periods when motor...
A question for our American friends. I'm in the UK and working on a US project.
When working with 4.16kV to 480V transformers. Is that the open circuit voltage or the full load voltage?
What should the motor nameplate voltage be when connected to the "480V" system?
Thanks
Matt
