Line Reactor Design, Functions, and VFD Applications
High-voltage transients or power disruptions from power grids can cause problems for industrial equipment, such as variable frequency drives (VFDs). VFDs typically come with some form of protection to mitigate power disturbances, such as metal oxide varistors (MOVs) or DC bus chokes. However, such components tend to lose their capabilities over time (natural degradation due to surpassed life span or cycles), which may result in unwanted damage to the VFD.
In order to keep the VFDs protected, businesses may consider installing a line reactor on the input side of the system.
