Overview of MV APFC capacitor banks
Automatic power factor correction with capacitor banks 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 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.

Benefits of MV APFC with Capacitor banks
-
◆Save money on electricity costs
The Electricity Authorities, force companies distributing electricity to apply financial penalties to utilities that have a substantial contractual power and low energy cosφ (generally 0,9). ZDDQ capacitor banks allow you to avoid penalties, which often are not reflected in the bill, and then are paid by the final user without even realizing it.Meanwhile,capacitor banks is widely convenient, both in the case of central and individual compensation, with Pay-Back less than or equal to 1 year.
-
◆Reduce investment costs
ZDDQ APFC Capacitor banks makes it possible to start out with a smaller system and, if necessary, expand the system by adding further modules later on.
-
◆Improve Power Quality
In many industrial electric plants supplied by MT there is a tension considerably distorted, due often to excessive load of MV/LV transformer. ZDDQ APFC Capacitor banks with a consequent load reduction by the transformer allow to bring it back to the operating conditions within the linearity limits, substantially reducing the voltage distortion. Furthermore the proper Power Factor reduces the presence of harmonic currents, and reduce heat, resulting in greater longevity and lower maintenance costs.
-
◆Maximizing equipment utilization
ZDDQ APFC Capacitor banks reduces the burden on transformers by providing the required reactive power locally, so that more consumers can be supplied by the same transformer.
Application fields of APFC with capacitor banks
ZDDQ APFC panel with 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.
