Medium voltage auto power factor correction capacitor panel 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 of MV APFC capacitor panel
Medium voltage Auto power factor correction capacitor panel aims to improve power factor and enhance power quality, utilising capacitors to offset usually inductive loads(motors).APFC system increase the efficiency of power supply, delivering immediate cost savings on electricity.
ZD-GWJ Series medium voltage APFC capacitor panel 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.

Benefits of MV Capacitor panel
■Fast return on investment through lower power costs
Power factor correction reduces the reactive power in a system. Power consumption and power costs dropin 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 Panels
ZDDQ APFC capacitor panel 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.
