How to Choose the Right Cable for Your Variable Frequency Drives
Posted on Thursday Nov 16, 2017 | powerflex, vfd, vfd-cables,
How are your connection your Allen-Bradley PowerFlex Variable Frequency Drives (VFD) to motors? Are you using THHN in pipe? Are you using shielded tray cable? Are you using motor supply cable? If you answered yes to any of these questions you might want to consider this. VFD cables from Belden offer greater performance over THHN because of the industrial grade insulation within the cable which results in a more reliable cable. VFD cables have a better shielding system that provides better protection for motors, bearings and drives.... {Read More}Get the performance you expect in a harmonic filter with TCI’s HarmonicShield.

The TCI, LLC HarmonicShield® (HSD) is a simplified 5% passive harmonic filter that provides performance in a cost-effective package. Based on TCI’s proven HarmonicGuard® Passive (HGP) filter design, the HarmonicShield (HSD) is designed for use with 3-phase diode bridge rectifier loads such as PWM drives. The optional contactor allows the tuning circuit to be disconnected at light loads to avoid leading power factor problems. Natural convection cooling means no moving parts. A lug kit option accommodates oversized cabling if needed. All of this is backed up by TCI’s 3-year warranty. The simplicity of the HSD design means you don’t pay for features you don’t need.... {Read More}Schaffner’s ECOsine® Active Eliminates Harmonics and Reduces the Cost for Reactive Power
Posted on Sunday Oct 16, 2016 | harmonics, reactive-power, vfd,
Whether for machinery, welding equipment, variable-frequency drives, or electric motors almost all non-linear consumers can cause substantial voltage distortion. Harmonic currents up to the 50th harmonic and expensive reactive power: ECOsine® Active eliminates both direct and reliable harmonic currents up to the 50th harmonic and expensive reactive power. This improves power quality and reduces cost. It’s easy to calculate the cost savings in reactive power, however, cost reduction due to less wear on equipment, less troubleshooting, or even prevented production downtime are more difficult to quantify.... {Read More}
