GGJ Low-Voltage Reactive Power Intelligent Compensation Device

Overview 

The GGJ low voltage reactive intelligent compensation device introduces microcomputer control by adopting computer- aided design (CAD),and carries out intelligent tracking compensation for reactive power.With reasonable structure and  advanced technology,it is widely used in low-voltage power grid,to enhance power factor,reduce reactive loss and improve power supply quality.As a new generation power saving product,it is specially used in the 130-600kVA three- phase transformer for reactive power compensation.

Features

+Controlled   by   intelligent   controller,full-featured.Reliable   performance,automatic   compensation;can   increase   the    power factor to 0.9 even higher.

+Real-time  display  of  grid  power  factor  and  range:lag  (0.00-0,99),ahead  (0.00-0.99).

+With    over-voltage,over-harmonic,over-compensation,system    failure,lack    of    phase,overload     and    other    comprehensive protection

+The  parameters  which  have  been  set  will  not  lose  after  power  failure,and  it  automatically  enters  into  running  mode power  grid  becoming  normal  without  operators  watching  over.

+According  to  the  grid  load  balance,take  phase  compensation  or  mixed  compensation.

+Strong  anti-interference  ability,can  withstand  the  interference  pulse  with  an  amplitude  of  2000V  directly  input  from grid,which  is  higher  than  the  national  professional  standards.

Environmental Conditions
