• To suppress harmonic current or improve the power factor of the power supply.
• When using an advancing capacitor switch.
• With a large capacity power supply transformer (over 600 kVA).
Note: Use an AC or DC reactor when also connecting a thyristor converter (such as a DC
drive) to the same power supply system, regardless of the conditions of the power
supply.

Connecting a DC Reactor
Ensure the jumper between terminals +1 and +2 (terminals are jumpered for
