CL Reactor - Specifications Tab

This field provides a list of industry standard reactor ampere ratings, but you can also type in a rating which is not listed.

3-phase reactor impedance kVA. This value is used to determine the impedance and X/R ratio of the reactor. If this value is not known, you must enter the positive and zero sequence impedance (X1 and X0) to compute the X/R ratio with the Calculate button. The Impedance kVA is calculated with the following equation:

Impedance kVA3ph = 3(IL)2(Xohm)/1000

Reactor material (copper, aluminum, or high-Q aluminum). This value is used to determine the X/R ratio of the reactor.

Positive sequence impedance. When filled in with the Calculate button, this field’s value is based on the reactor impedance kVA.

Zero sequence impedance. When filled in with the Calculate button, this field’s value is considered the same as the positive sequence impedance X1. If you enter this value as zero (0.0), the positive sequence impedance is used.

The reactance to resistance ratio of the reactor. When filled in with the Calculate button, this field’s value is based on the impedance kVA and the material type of the reactor.
