Overview of MV Harmonic Filter Capacitor banks

Medium Voltage Metal Enclosed Harmonic Filter Capacitor Banks aims to improve power factor and enhance power quality, utilising capacitors to offset usually inductive loads(motors). SVC APFC system  increase the efficiency of power supply, delivering immediate cost savings on electricity.

ZD-GWJ Series Medium voltage automatic power factor correction panels with filters : 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 

■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.
