Comparative study of passive transients controlling methods during capacitor bank switching

Most of the domestic, industrial and agricultural loads are inductive in nature which results in lagging power factor further corresponding to power losses at substation level to consumer level. To avoid this, capacitor banks at large scale are installed at the substation (near to the source). As every boon comes with a bane, capacitor banks too causes high frequency and high current transients during switching of the capacitor banks. This paper deals with the comparison of various methods which use a passive element like resistor in various configurations to control the peak value of transient currents in a 11KV distribution system.
