Line Reactors

An individual usually utilizes input or line reactor to protect VFD (Variable Frequency Drive) from input power line disturbances that can damage the drive or create nuisance tripping. It also helps in lowering the harmonics generated by VFD back onto the power line.
Line reactors are linked in between input source and VFD controller series.Mounted closer to the drive. Output or load reactor is used for motor protection where distance of wiring between VFD and motor is longer. High frequency PWM 3-phase output is generated by the drive with noise spikes over the leading edge of frequency. These spikes get increased because of lengthy cables and their extra capacitance. This results in high voltage rating for motor where insulation breakdown happens. Manufacturers of Line and Load Reactors are fabricating their entire range with great enthusiasm and dedication to bring high-performing designs for the clients. They also provide installation facility on request.
