How to increase 3-Phase voltage from 208v to 230v

I needed to increase the voltage/power for a machine to be installed at one of my customers. It is a very large Press-Brake. The machine is used to bend large pieces of metal. The nature of the machine requires sudden usage of power when the large pitman arm of the press brake has to be stopped. They use an electromagnet. Those of us with experience in this know you can get voltage dips due to the magnet saturating or collapsing. This dip will cause some electronics to fault out. The solution is in this video
