I have been asked to add a buck/boost transformer to help correct a voltage issue for a lake fountain motor. I have read this link http://forums.mikeholt.com/showthread.php?t=144958&page=3 and from what I gather is that if a transformer were to be added to adjust the voltage from 208V to 230V the transformer would need to be sized 3-5X larger to account for the inrush?? The actual information for this particular situation is a single phase 230V rated 3HP motor (lake fountain) is currently running on 208V from a 3 phase wye system. The distance from the source to the motor is approx. 250' and the actual voltage under load at the motor is 192V. The motor has quit working already after only running for about a month for approx. 8 hours a day. I haven't ever installed a buck/boost transformer and I am just searching to see if this is a practical fix or not...or should the fountain contractor just replace the motor with a 200v rated one...seeing as how it sounds like it may be toast already. FYI: There is a capacitor in the control panel I am assuming is to help compensate for some of the inrush on start up.
