Reactor Accessories
Reactor accessories are critical components used in variable frequency drive (VFD) applications to protect drives, motors, and power systems from electrical disturbances. These products help reduce harmonic distortion, voltage spikes, and current ripple that can negatively impact equipment performance and longevity. Reactor accessories are commonly used in industrial motor control systems where reliability and power quality are essential.
This category includes line reactors, load reactors, and VFD filters designed for applications up to 1500 horsepower. Line reactors are installed on the input side of a VFD to smooth incoming power, reduce voltage distortion, and limit harmonic currents reflected back into the electrical supply. By introducing impedance between the power source and the drive, line reactors help protect the VFD’s input circuitry and improve overall system stability.
Load reactors are installed between the VFD and the motor to reduce voltage stress and condition the PWM waveform produced by the drive. Standard PWM outputs generate fast-rising voltage pulses with sharp edges that can damage motor insulation and increase cable heating. Load reactors soften these transitions, reduce peak voltage, and help motors and cabling operate cooler with less electrical stress. Reactor accessories are widely used in applications involving long motor leads, high-speed switching, and inductive motor loads.
FAQs
Q: What are reactor accessories used for in VFD systems?
Reactor accessories are used to protect variable frequency drives and motors by reducing harmonics, limiting voltage spikes, and improving power quality within motor control systems.
Q: What is the difference between a line reactor and a load reactor?
A line reactor is installed on the input side of a VFD to protect the drive from line disturbances and reduce harmonics. A load reactor is installed on the output side to protect the motor and cable from voltage stress and waveform distortion.
Q: Why are VFD filters and reactors important for motor protection?
VFDs produce PWM waveforms with fast voltage transitions that can stress motor insulation. Reactors and filters soften these transitions, reduce peak voltages, and extend motor service life.
Q: What types of loads benefit most from reactor accessories?
Inductive loads such as motors, pumps, fans, and compressors benefit most from reactor accessories due to their sensitivity to voltage spikes and current distortion.
Q: How do reactors reduce harmonics in a power system?
Reactors introduce inductive impedance that slows the rate of current change, stabilizes the waveform, and reduces harmonic currents drawn from or injected into the power system.
