Medium voltage automatic power factor optimizer are very beneficial in power grids. They provide the reactive power needed by electrical motors, transformers, etc. This increases the transmission capacity and reduces losses thanks to higher power factors. They enable power factor targets of the utilities to be met. Meanwhile, it also a key component in various filter solutions that reduce harmonic content. They reduce the risk of disturbances in production processes, metering errors and malfunctioning of relay protections. This extends the service life of connected equipment.
Overview of Local APFC
M.V Automatic power factor optimizer aims to improve power factor and enhance power quality, utilising capacitors to offset usually inductive loads(motors).Automatic power factor optimizer increase the efficiency of power supply, delivering immediate cost savings on electricity.
ZD-GWJ APFC Panels : 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.

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.
Application
ZDDQ automatic power factor optimizer 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.
