Mitigation of Voltage Drop Using Pre-insertion Resistors

... The phase shifting transformer was first energized with preinsertion resistor on Oct 15, 2008. A high inrush current with peak value of 3.2 kA was observed in Phase A and this resulted in an unexpected large voltage drop of 17% as shown in Fig. 7. The high inrush current was considered to be due to ...

Electrical ballast



An electrical ballast is a device intended to limit the amount of current in an electric circuit. A familiar and widely used example is the inductive ballast used in fluorescent lamps, to limit the current through the tube, which would otherwise rise to destructive levels due to the tube's negative resistance characteristic.Ballasts vary in design complexity. They can be as simple as a series resistor or inductor, capacitors, or a combination thereof or as complex as electronic ballasts used with fluorescent lamps and high-intensity discharge lamps.
