Shunt reactors are pure inductive coils that deliver their rated power to the grid in the form of inductive current. They are installed as shunt components directly connected to the main busbar.

What does Inductive Load Means?
What does inductive load means? Inductive loads are electrical components characterised by an inductance value. Such components include devices such as motors, transformers and induction ovens. Inductive loads react to changes in current and typically reduce the power factor in electrical systems. As a result, the power factor may decrease due to inductive loads, necessitating the use of inductive load reactors to improve the power factor.

What is a Shunt Reactor?
Shunt reactors are purely inductive coils that deliver inductive current to the grid at their rated power. These devices, connected in parallel to the main busbar, are used to compensate for capacitive effects, particularly at low load levels or on long cable lines. They prevent the system from reaching the capacitive penalty threshold during voltage increases.
Benefits of Shunt Reactors
Shunt reactors balance the capacitive load in electrical systems, thereby improving the power factor. The key benefits of shunt reactors are as follows:
- Elimination of the capacitive load generated by cables and avoidance of associated capacitive reactive energy charges: Long cables in electrical systems can cause a capacitive effect, contributing capacitive reactive power to the power system. Shunt reactors counteract this situation by avoiding the payment of capacitive reactive power charges, thereby reducing energy expenditure.
- Non-payment of capacitive reactive energy charges in facilities with solar power plants during periods of no consumption: In solar power systems, capacitive reactive energy can build up in the power system during periods of low or zero consumption. Shunt reactors can compensate for this capacitive reactive energy, preventing the need to pay associated charges and thereby reducing operating costs.
- Utilization in facilities equipped with large and powerful UPS systems : Shunt reactors play a critical role in facilities with large, high power UPS systems. These UPS units are essential for maintaining system operations during unexpected power failures. To operate effectively, UPS systems require the correct power factor. By regulating the power factor, shunt reactors enable large, powerful UPS systems to operate more efficiently and improve the overall reliability of the systems.
Low-Loss:
Shunt reactors have minimal energy losses when converting electrical energy. This means that they convert less energy into heat during operation, resulting in more efficient energy utilisation within the system.
Extended Operational Lifespan:
High-quality materials and robust design contribute to the long service life of shunt reactors. With proper use and regular maintenance, these reactors can operate smoothly for an extended period.
Copper Terminals:
The shunt reactors typically feature copper terminals due to copper’s high conductivity, which allows for efficient transmission of electrical current and enhances the overall performance of the reactors.
Varnished Under Vacuum:
Reactors are typically varnished under vacuum to shield their internal components from corrosive effects and provide insulation. This process ensures the longevity of the components within the reactor and enhances its reliability.
Noiseless Performance:
High quality, well engineered shunt reactors typically operate at low noise levels, helping to minimise disturbance and improve the working environment within electrical systems.
