Reactors
Reactors for managing various electrical parameters

Neutral generators

It is a three-phase reactor connected to the power system to obtain an effective phase-neutral reference in systems where it does not exist or is unreliable. 
This type of grounding reactor can also supply a three-phase source of auxiliary services.

Current limiting reactors

Current limiting reactors are used to limit ground fault current to preset values that can be handled by the switching equipment.
 

Compensation, parallel, or shunt reactors

These are used to compensate for capacitive reactive loads on lines and the system in general. They are normally placed at ends or at specific points.
