Abstract:
1. A system for compensating for a voltage dip and undervoltage, comprising, a transformer with a primary side and a secondary side, wherein said secondary side contains switches and a sufficient number of taps; a voltage dip/swell detector electronically coupled to said primary side; and a level detector/switch selector device electronically coupled to said voltage dip/swell detector; wherein said level detector/switch selector device is electronically coupled to said secondary side of said transformer, wherein the primary side and the secondary side are directly and electronically coupled to a common supply voltage, and wherein said voltage dip/swell detector is comprised of a relay with inverter, a low pass filter, an absolute value generator for a rectified source voltage signal, an absolute value generator for a reference source voltage signal, and a comparator.
