Shunt reactors are commonly used to compensate the capacitive reactive power of transmission lines and thereby provide a means to regulate voltage levels in the network. These reactors can be applied directly at transmission level, but the cost of switchgear, maintenance of oil-cooled iron core reactors, and possible saturation at high voltage levels favour the use of air core reactors at ...

Shunt reactors. Shunt reactors are used in power systems to counteract the effect of the line parasitic capacitance, thereby stabilizing the system voltage within acceptable limits. The utility of shunt reactors for voltage control on lightly-loaded transmission lines was examined in a 1926 paper presented at the AIEE by Edith Clarke. For short lines, we can basically ignore the impact of ...

Shunt reactors carry small currents, typically 300 A or less. It is relatively easy to interrupt small currents at first. When the current extinguishes, the shunt reactor voltage oscillates toward zero at the reactor natural frequency, typically 1 to 5 kHz. The supply side varies at 60 Hz power frequency.
