Comparison Between Static Capacitors and Synchronous Condensers

The comparison between static capacitors and synchronous condensers can be done in the factors like power factor, overloading, kVAR, stability of the system, power loss,  installation, change of rating and failure are listed below the table.

S.no
Static Capacitors
Synchronous Condensers
1 Better control of the power factor is possible. Better control of the power factor is not possible.
2 Overloading for a short time interval is possible. Overloading is not possible.
3 Greater kVAR is supplied when there is a voltage drop. Less kVAR is supplied when there is a voltage drop.
4 The stability of the system is improved due to the existence of inertia. The stability of the system remains unchanged.
5 Power loss in the system is high. Power loss in the system is low.
6 Installation can be at only one point. It can be installed at any point in the system.
7 The rating cannot be changed. The rating can be changed.
8 Difficulties exist in the installation. Installation is easier.
9 Less failure rate of the system. The high failure rate of the system.
10 Suitable and economical, where the requirement of kVAR is more than 10,000. Suitable and economical, where the requirement of kVAR is small.
