High voltage automatic power factor control/reactive power compensation systems are used everywhere that motors are still directly operated without power electronics, or other consumers with a low inductive cosφ place strain on the grid with reactive power in addition to their active-power requirements. Local supply of this reactive power by means of compensation systems relieves the burden on the supply grid and reduces losses.
Overview
High voltage Automatic Power Factor Control (APFC) Panel based on Static Var Compensator(SVC) aims to improve power factor and enhence power quality, utilising capacitors to offset usually inductive loads(motors). HV APFC system increase the efficiency of power supply, delivering immediate cost savings on electricity.
ZD-GWJ high voltage automatic power factor correction panels for motors and VFDs: can detect the reactive power needed by the system in real time,compare it with the set value, carry on the automatic intelligent capacitor-switching on/off, make the reactive power of the system achieve dynamic balance, in order to improve the power factor of the system, stabilize the system voltage.
Following are effect before and after power factor correction,

HV APFC PANEL Capacitors and Reactors
Features of HV APFC
■Fast return on investment through lower power costs
Power factor correction reduces the reactive power in a system. Power consumption and power costs drop in proportion.
■Effective use of installation
An improved power factor means that an electrical installation operates more economical (higher effective power for the same apparent power).
■Improved voltage quality
■Reduced voltage drops
■Optimum cable design
Cable cross-sections can be reduced with improvement of power factor (less current). In existing installations for instance, extra or higher power can be transmitted.
■Reduced transmission losses
The transmission and switching devices carry less current, i.e. only the effective power, meaning that the ohmic losses in the leads are reduced.
Application fields of MV Capacitor banks
ZDDQ automatic capacitor banks are widely used for fluctuating loads such as motors, variable frequency drives, melting furnace from Steel Rolling mills,Chemical industry,Cement plant, Suger plant, Textile, Hospitals, Hotels, Building segment,Automobile industry,Oil and gas industry,public grid etc.
