On a 120 volt base, the load voltage is . 16.8 Three-phase voltage regulators. Three-phase regulators may be obtained by interconnecting 3 single-phase regulators. There are four different ways in use for connecting single phase regulators for three-phase circuit regulation. They are: Three regulators connected in grounded-Y.
