Inductors―Part 1 The Basics of Inductors ①｜Electronics …
Along with resistors and capacitors, inductors (coils) are one of the three major passive component categories for electronic devices. Coils exhibit special characteristics when a current passes through them, and through the utilization of these characteristics, inductors play an important role in power supply circuits, general signal circuits, and high frequency …
Reactors in a Power System
A reactor, also known as a line reactor, is a coil wired in series between two points in a power system to minimize inrush current, voltage notching effects, and voltage spikes. Reactors may be tapped so that the voltage across them can be changed to compensate for a change in the load that the motor is starting.

What''s the role of capacitors in this circuit?
What''s the role of the capacitors? The two 470 pF are in series across the line so, ignoring the 47 pF capacitor, the two 470 pF act together as a single capacitor of value of 235 pF. This is commonly used and, it ensures that any RF pickup on the cable that might otherwise feed into the transformer (as a differential signal) is largely "shorted" …
