CUTTING IT VERY CLOSE IS AN UNDERSTATEMENT 15kV RMS x 1.414= 21.21 kv or 100
volts over the rated voltage of your capacitor string. That is not saying it
will not work as the capacitors are designed to tolerate a small over
voltage, but consider you may have a 5% primary voltage rise in your power
now you have 1000 volts more or 22Kv on your capacitors. It is a lot safer
to design your capacitor to tolerate more voltage than it is to under design
your capacitor.
