What is the purpose of a line reactor in a power system?

A line reactor is an inductor placed in series with a power line to reduce harmonics, limit current surges, and protect electrical equipment from voltage spikes.

This video explains the benefits of using a line reactor with a Variable Frequency Drive (VFD) system. Line reactors help reduce harmonics, limit current surges, and protect equipment from voltage spikes, improving overall performance and power quality. The video details the different types of line reactors, including open-style panel mounts and standalone enclosures, and the importance of selecting the correct impedance rating (3% or 5%) for optimal protection. It highlights the impact on extending VFD lifespan, preventing motor overheating, and ensuring compliance with power quality standards.
