Why i used dv/dt filter for VSD but still have cable lenght limite
Why i used dv/dt filter for VSD but still have cable lenght limite
(OP)
As i found on many seller VSD catalogue that we can extend cable lenght by use dv/dt filter for mitigation overvoltage at motor side but after we added dv/dt we can extend lenght of cable only 50 -100 m . Can we use more than ?
This limitation is for EMC standard reason or technical reason

Exactly what those limits are varies by voltage, motor hp, drive carrier frequency, motor insulation class, and other things.
This isn't a surprise now, is it?
