GGJ Series Reactive Power Compensation Device
GGJ Series Reactive Power Compensation Device
Reactive power compensation device is indispensable in power supply system, mainly to improve the power factor of power grid, reduce the loss of power supply transformer and transmission line, improve power supply efficiency. Reasonable selection of compensation devices can minimize the loss of power grid. However, if it is improperly selected or used, it may cause many problems such as voltage fluctuation and increased harmonic in power supply system.
Normal Operating Conditions
Problems caused by high reactive power:
  • It will increase the current and loss of transmission lines and waste electric energy;
  • If the distance of transmission lines with increased current is long, the voltage on the lines will decrease greatly, and the lower voltage may affect the normal use of the equipment.

After the capacitance compensation:
  • Increase the voltage of busbar and feeder.
  • Reduce the total current of incoming lines of power station.
  • Increase the load capacity of the transformer.
  • Improve the power factor.
  • Reduce the transmission of reactive power and power loss on transmission lines.
  • Improve the utilization rate of equipment.

Note: The special written instructions are required when ordering beyond the NORMAL OPERATING CONDITIONS.
