Allen-Bradley 1321 Power Conditioning Products 1321-RWR100-DP

The 1321-RWR100-DP line reactor is designed to serve as a power conditioning device that effectively limits the transmission of extreme over-voltages generated as a by-product of the circuitry of insulated gate bipolar transistors (IGBTs) for Pulse Width Modulation (PWM) in the inverter section of the majority of Variable Frequency Drives (VFDs). These over-voltages, if left unattended, can cause electrical arches in the windings of the motors, known as partial discharges or a corona effect, and these arches can damage insulation and rendering the systems unusable. Another consequence of overvoltages produced in the VFDs is the reflected wave phenomenon, in which as a result of the different impedance levels of the cables and motors, high spikes of energy are reflected to the drive, accelerating the deterioration of the system’s insulation.
