Taiwan High Quality Capacitor Manufacturer – YUHCHANG

YUHCHANG Electric Co., Ltd., established in April 1967, is one of professional large capacitor manufacturers in Taiwan. We specialize in manufacturing in power capacitors, dry type capacitors, high and low frequency capacitors, reactors, automatic capacitor banks, low voltage capacitor and automatic power factor regulators.


Capacitors of Selection and Recommend


  1. Consider harmonics in power system, the specification of capacitor should use higher rating voltage.


  1. In case of automatic power factor regulation bank, due to frequently switch in and out as well as the effect of inrush current, the capacitors should properly be equipped series reactors and use higher rating voltage specification.


  1. Consider voltage rise problem when capacitors connected with series reactors.
  • For 6% series reactor (XL/XC-6%), capacitor voltage rise 6.38%
  • For 8% series reactor, capacitor voltage rise 8.7%
  • For 13% series reactor, capacitor voltage rise 14.94%
  • Capacitor voltage rise rate = [(1/ (1-XL/XC))-1] x100%


  1. Calculation coefficient for capacity (kVAR) variation after increasing rated voltage of capacitor.
