Have a vendor that uses Variable Frequency Drives and when the utilities capacitor banks kick in it causes a distroution in the voltage. Any Ideas on how to start sizing the choke and where can you find them.

Steady state cross the line stater. I found through monitoring that the voltage drop decreases with the impedences of the system. IE as it gets further away the drop lessens.

3000hp motor 5000 kva transformer

I have a motor that caused a 21% voltage drop on the secondary side of a transformer with neg impedence. Would the voltage drop on the primary side be 21% or would if be a function of the turns ratio also.

Passed EE power. Great to not have to study that hard again! :party-smiley-048:

This is driving me crazy!!!!!!!!!!!!!!!!!!!!!!!!!!! I'm in Knoxville and it was like this for the Oct. test. I thought for sure it would be here by now.
