Energy security is a prerequisite for any country that aspires to prosper. A country’s power transmission and distribution network thus plays a pivotal part in its overall economic development. This has prompted countries to renew their commitment to building a robust energy infrastructure, thus accelerating the growth of the global shunt reactor market.
A shunt reactor, by virtue of absorbing reactive power, plays a crucial role in increasing the energy efficiency of a power transmission system. High-voltage transmission lines and cable systems need effective reactive power compensation to protect them from the spike in voltage levels that can cause irreparable damage. A shunt reactor can be either directly connected to a transmission line or to a three-winding transformer’s tertiary winding. Some facilities deploy a permanent connection between the shunt reactor and the power line, while a circuit breaker is used in some cases. Shunt reactors with variable ratings are used in power lines where load variation is slow so as to optimally adjust the consumed reactive power. The role of shunt reactors is thus crucial in power transmission lines that cover a large area.
