3) Harmonic current capable of absorbing.

Each step is formed by 2 reactors and a 6 terminal capacitor which contains 2 three-

phase, 3 terminal capacitors each electrically insulated. The operating principle of this

design is that each reactor is connected to each of the three capacitor terminals forming

an LC set tuned to a frequency close to the 5th harmonic and another set tuned near to

the 7th harmonic. The following diagram shows how the step is formed:

Filter regulation

Filter regulation is via a conventional power factor regulator as with any other standard

capacitor bank. (See regulator manual)
