How can i make power factor for three phase

 

Perhaps you could make your question a little clearer. I'm not sure of what you are asking.

i mean improve the power factor for the three phase line to make voltage and current in phase

 

If the uncompensated power factor is lagging you can use power factor correction capacitors specifically designed for that purpose. What's your particular application?

 

Capacitor Bank in parallel with the load will improve the power factor.

 

It depends on t_n_k's question, what is the application?

For example, does the industry in its entirety all turn on and off at the same time? The solution would be a fixed value of PFC.

Conversely, would it be easier to switch capacitors in-and-out through a PLC governed by a PF that varies?
