7.2.1 AC reactor

Using AC reactor can restrain higher harmonic wave and improve power factor
obviously. In the following situation, users are advised to use ac reactor.
●Ratio of capacity: power supply source: Ac drive>10:1
●Silicon controlled load and switching controlled power factor compensator in a same
place.
●Degree of three-phase voltage unbalance is more than 3%
