Hi;
I don't know %reactance of the reactor but I calculate from voltage drop, it's about 10% of system.
Specification of reactor:
I 1870 A
L 4.8 mH

Hi;
Thank you to prc, Yes, My plant have an arc furnace and my system have the SVC system for 2'nd, 3'rd,4'th harmonic filter total power = 100 MVA and now I used only 2'nd,3'rd and have pf=0.9957
So I think the 3'rd harmonic should be a SVC's Function.

Hi;
Thank you to Ralph, So I contact to ABB's representator in the next time. Yes I worry very much about volatge drop on series reactor because my process need the voltage and power for increase the pocess time but not need change the transformer.
Before I post this problem , I check...
Hi;
My factory worked since 1992, I check the power circuit of power transfermer and found a point of loss as this follow.

I have some problem in water pump group motor in my factory. I must be change a motor's bearing every 1-2 month because the shock pulse value exceed standard value
(~35db). I check everything and found
1. The grease (type shell R3) in Brearing non-drive change to liquid status...
