Special Transformer

 

Features

  • Improvement of power system's stability and transmission line efficiency while maintaining the voltage fluctuation of voltage system
  • Air gap consists of one core installed core leg, winding, tank, and accessories.
  • Outline dimension, loss and materials to be used are relatively smaller than the series reactor (self-shielding type)
