RC protection for surges
RC protection for surges
(OP)
Hello!
I'm looking for hints on how to design the RC protection for large motors started and protected with vacuum breakers. I have read that together with surge supressors there is a need for RC group surge protection to limit the steepness of voltage rise.
I know that usually you have to make a EMTP programme simulation but it is very complicated and time consuming (not to mention you have to be an expert). Maybe somebody has already found an article/ recommendation for the design method for such a RC group.
Thanks!

Bus if the motor is fed from a VFD or a soft starter, search this forum for a recent discussion of the problems with using capacitors.
