Synchronous Condenser
At the point when a synchronous motor works at no-load and is over-excited, it is known as a synchronous condenser. At the point when a synchronous motor is over-excited, it gives driving current and works like a capacitor.
In a synchronous motor, a separate DC source is utilized to excite the field winding. Thusly, the input supply just gives current to energize the stator, i.e., the current gave is in-phase the supply voltage. So the power factor remains unity.
The power factor can be changed by shifting the DC excitation. By expanding the DC excitation, the power factor fluctuates from lagging to unity and driving power factor. At the point when the DC excitation builds, the field windings are over-magnetization. The input supply gives an current part to the stator to make up for this over-magnetization. This current leads the supply voltage, causing a main power factor or creating reactive power.
A capacitive load generates reactive power, whereas an inductive load consumes reactive power, resulting in a leading power factor. A synchronous motor can be utilized to further develop the general power variable of an electrical system by changing the DC excitation. The synchronous motor utilized explicitly for power factor improvement with practically no mechanical load is known as a synchronous condenser.
The synchronous condenser is utilized in parallel up with the load to further develop the power factor. Further developing the power factor lessens the additional current drawn from the source that is squandered in the electrical cables. Subsequently, it helps in the decrease of power bills and saves energy.
A synchronous condenser draws leading current and partially eliminates the reactive component when connected across the supply voltage (in parallel). Along these lines, the power factor is gotten to the next level. In most large industries, synchronous condensers are used to raise the power factor.

Power Factor Improvement
Power factor improvement is an indispensable piece of optimizing electrical systems for expanding effectiveness and diminished energy utilization. In the space of electrical designing, power factor is the extent of how effectively electrical power is changed over into important work output. The power factor has a worth somewhere in the range of 0 and 1, with a worth of 1 addressing ideal effectiveness. In numerous modern and business settings, power factors will in general go amiss from solidarity as a result of the presence of responsive power parts, prompting diminished system productivity.
This article aims to uncover knowledge of the significance of force factor improvement and the various methodologies used to overhaul power-enhanced electrical systems. As ventures have a go at energy productivity and supportability, understanding and having a tendency to drive factor issues become foremost. Businesses can not only reduce their energy consumption to a minimum while also contributing to a more environmentally friendly and cost-effective operation by learning the fundamentals of power factor improvement.
