| Power Factor Controller | |
|
DESCRIPTION |
| It measures system power factor and automatically switches the capacitor banks on/off as required by plant load to maintain desired power factor. Target power factor range is programmable from 0.8 (lag) to unity and dead band setting is provided to avoid over-correction and hunting. Capacitor switching is in sequential method (first in- last out). This method is applicable for equal value capacitor banks, and can be changed to ascending or descending order wherever needed. | |
| Power Factor Controller can be used to eliminate power factor penalty fees from power utility bills by automatically maintaining system power factor within a set range. | |
