hello everyone, the reason of my question is how to mitigate the vontage sag originate by the external grid to feed several plastic film making machines which are very sensitive the voltage sags. the the voltage operation is 480 volts 3 ph 60 Hz from 1500 KVA internal distributoion power transformer transformer. should it be possible to mitigate to solve this problem out connecting a PWM autotransformer?? as far as I know other solution result more expensive.
Just awaiting for yours comment

Dear Sir
Pls verify the operating voltage for your machine because the voltage and frequency is main.

I can ratify the voltage 480 V & 60 HZ the proble is the effect of the voltage sag
