WITH A DRIVE ISOLATION TRANSFORMER, LOAD DISTURBANCES CAUSED BY THE SCR DRIVE ARE MINIMIZED

Posted on Friday Jun 07, 2019 | drives, scr, transformers, vfd,

DRIVE ISOLATION TRANSFORMERA transformer is needed to magnetically isolate incoming lines on Silicon Control Rectifier (SCR) variable speed motor drive applications. For the required voltage of the SCR drive to match a transformer must also provide a voltage change. ... {Read More}

Fluke Motor Drive AnalyzersThe idea behind Fluke’s 510 and 550 Motor Drive Analyzers is that it is easy for people to pick up and use. They didn’t want it to be something where people needed to remember a sequence of buttons to press. ... {Read More}

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.

Posted on Friday Jul 07, 2017 | filters, harmonics, vfd,

TCI HarmonicShieldThe 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,

Schaffner Active FilterWhether 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}
