Overview of HV Capacitor banks
Automatic Capacitor banks based on Static Var Compensator(SVC) aims to improve power factor and enhence 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 High voltage automatic capacitor banks : 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,

Features of HV Capacitor banks
■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.
Applications
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.
