Synchronous condenser is an over-excited synchronous motor operating at no-load with leading power factor.
The efficiency of long power transmission lines may be increased by placing synchronous condensers along the line to compensate lagging currents caused by line inductance.
More real power may be transmitted through a fixed size line if the power factor is brought closer to unity by synchronous condensers absorbing reactive power.
The ability of synchronous condensers to absorb or produce reactive power on a transient basis stabilizes the power grid against short circuits and other transient fault conditions

Introduction
A synchronous condenser is a device used in electrical power systems to improve power factor and voltage regulation. It is essentially a synchronous motor that operates without any mechanical load. The correct answer is option D, and in this explanation, we will discuss why it is the correct choice.
Explanation
A synchronous condenser is an over-excited synchronous motor operating at no-load with a leading power factor.
- A synchronous condenser is a synchronous motor that operates without any mechanical load. This means that it does not perform any useful work like driving a pump or a fan. Instead, its sole purpose is to improve the power factor of the system it is connected to.
Over-excited synchronous motor
- A synchronous condenser is over-excited, which means that its field current is higher than the current required to produce the rated voltage. This over-excitation creates a leading power factor, which helps to compensate for the lagging power factor of other loads in the system.
No-load operation
- The synchronous condenser operates at no-load, which means that it does not consume any real power from the system. It only absorbs reactive power, which helps to improve the power factor of the system. By absorbing reactive power, the synchronous condenser helps to balance the reactive power demand and supply in the system, thus improving the overall power factor.
Used in large power stations for power factor improvement
- Synchronous condensers are commonly used in large power stations to improve the power factor of the system. Power stations often have a mix of loads, some of which may have a lagging power factor. By connecting a synchronous condenser to the system, the power factor can be improved, leading to better voltage regulation and reduced line losses.
Conclusion
In summary, a synchronous condenser is an over-excited synchronous motor that operates at no-load with a leading power factor. It is used to improve the power factor of a system, especially in large power stations.
