Power Quality Analysis
Capacitor failure due to harmonic distortion

Automated warehouse reclaimers use variable frequency drives to control the speed of each robotic reclaimer. The PLC controls and VFD electronics are sensitive to electrical power quality anomalies in the network.    

These are some of the typical issues:

  • Rectifier failure of VFD’s.
  • Time delays due to resetting during malfunction of equipment controls.
  • Nuisance stopping of electronic equipment.
  • Electrical breaker tripping and unplanned stoppages.
  • Scrapping of material and delay in cleanup time.  
  • Premature failure of electronic equipment.
  • Sensor data malfunction.

Common Power Quality Issues Causing these Problems

Voltage Sag

Voltage Sag/Dips

Voltage sags are the primary cause of unplanned production stoppages in industry. Causes include electrical network faults due to weather, animals across terminals, traffic accidents, load switching upstream, startup of large loads or transformer energization.

Voltage Transiets

Voltage Transients

A sudden change from the nominal voltage or current may be caused by faults in the network, switching of large loads, load shedding, or switching of capacitor banks upstream in the utility network. Voltage surges also occur but may be less severe.

Power Interruption

Momentary Power Interruptions

Momentary power loss is complete loss of voltage on one or more phase conductors between 0.5 cycles and 3 seconds.  The most common forms of power failure are due to utility protection systems, e.g. recloser operations, switching, breaker tripping and equipment failures.

Harmonic Distortion

Current & Voltage Harmonic Distortion

The use of non-linear loads is the main cause of harmonic distortion. The injection of harmonic currents results in voltage distortion which may cause electronic equipment failure, increased heat in drives and transformers, unwanted tripping, malfunction of sensitive equipment and controls and failure of imaging and scanning equipment.
