Solutions to Voltage Dip Process Interruption

Momentary dips or sags in supply voltage to industrial or power plant auxiliary systems, are often the cause of process interruption or downtime.  These dips are caused by lightning strikes on lines, short circuits or faults on the supply or auxiliary system.  Voltage sagging is caused by switching of heavy loads such as starting of large motors and bulk load. 

Dips or sags will effect electrical some tripping immediately and others such as motors will loose torque and drop in speed. 

Motor and other control systems will normally shutdown very quickly stopping drives essential for the continuous running of the plant.   Our expert engineers have many years of experience and have implemented voltage dip proofing solutions on several plants in the past.  

Our Solutions

IGS quality plans and procedures are based on world best practices and results.  The process is shown in the figure on the right hand side.  Past events are carefully studied and problem areas are identified.  A voltage dip and sag strategy is then defined and tested against the plant capabilities.  An example of such an strategy compiled by our experts is shown below.  Potential modifications are then identified  and their impact is assessed.  Economic assessments are done finding the mitigation plan with the best economic value. 

IGS uses the latest technology and methods that have been proven in practice.  One such solution is the DPI or Dip Proofing Inverter.  Read more about this unique product by clicking here.
