How are series capacitors installed on a transmission line?

Because series capacitors are installed in series on a transmission line, the equipment must be elevated on a platform at system voltage, fully insulated from ground . The capacitor bank together with the overvoltage protection circuits are located on this steel platform.

How does a series capacitor work in a transmission system?

In a transmission system, the maximum active power transferable over a certain power line is inversely proportional to the series reactance of the line. Thus, by compensating the series reactance to a certain degree, using a series capacitor, an electrically shorter line is realized and higher active power transfer is achieved.

What is a fixed series capacitor?

The fixed series capacitors are the most cost-efficient solution. Their simple, proven and robust technology supports transmission system operators by optimizing power transmission and increasing transmission capacity. Siemens Energy is proud to reiterate: All major components are sourced in-house.

What is fixed series capacitor (FSC) technology?

For decades, fixed series capacitor (FSC) technology from Siemens Energy has improved grid stability and contributed to the optimal utilization of transmission lines. Transmission system operators around the world have already benefited from solutions that were tailored to their specific requirements.

Why does Siemens Energy offer fixed series capacitors?

Due to this complexity Siemens Energy recommends and offers individually designed solutions with fixed series capacitors. Siemens Energy' fixed series capacitor (FSC) systems increase the transmission capacity of both newly built and existing lines and also help to improve the quality and stability of power transmission lines.

What are the benefits of fixed series capacitor?

Among the main benefits of FSC are the reduction of line voltage drops, limitation of load-dependent drops, and a reduction of the transmission angle. Increased maximum capacity Fixed series capacitor expands the transmission capacity of lines by compensating the impedance of the overhead line.
