PQIS Power Quality Analysis

Analysis of industrial LV Supply was carried out by PQIS for industrial business in Wigan.

The graph below illustrates the consequence to power quality of low power factor. The KVAR reactive power is high, inflating the KVA maximum demand way beyond the KW.

To improve the power factor a 600KVAR Static VAR Generator has been recommended.

The graph below is from another LV Supply achieving a good power factor with an SVG unit connected to the supply. The KVA maximum demand is closer to the KW and the KVAR reactive power is near eliminated.

This will increase capacity and efficiency for the supply and reduce electricity costs.
