Terminologies of Ferranti Effect
- Ferranti Effect: The Ferranti effect is a phenomenon where the voltage at the receiving end of a long transmission line is higher than the voltage at the sending end. It happens because of the capacitance of the transmission line, causing reactive power flow.
- Capacitance: Capacitance is the capacity of a system to store an electric charge. With respect to the Ferranti effect, it plays a major role as the capacitance of transmission lines used for the gathering of reactive power, causing voltage rise.
- Surge Impedance Loading (SIL): The maximum power transfer capacity of a transmission line without causing overvoltage is known as surge impedance loading. It is a basic parameter in preventing unnecessary voltage rise related with the Ferranti effect.
- Reactive Power: Power oscillations between a system’s load and source are referred to as reactive power. In the Ferranti effect, the transmission line’s capacitance induces reactive power flow, adding to voltage rise.
Ferranti Effect
As we know electricity is generated at power generation plants using huge electromechanical generators by conversion from different types of energy. After that, a long-distance transmission line carries this electrical energy to the end users. In order to maximize the effectiveness of the power transmission and distribution system and ensure the safety of the connected loads and personnel, the electrical power transmission lines require a variety of safety devices and components. The transmission line faces different types of losses and characteristics that influence its efficiency. The Ferranti Effect is one such phenomenon that has a significant impact on the transmission line.
For the most part, we assume that the voltage generally drops in the transmission lines because of the line losses. In a long-distance transmission line with a very low load or no load at all, the Ferranti Effect causes the receiving voltage to be higher than the sending voltage.
In this article, we will be going through the Ferranti effect, First, we will start with the basics of the Ferranti Effect, Then we will go through the Causes of the Ferranti Effect, After that we will go through the Ferranti Effect in Transmission Lines and ways to reduce Ferranti effect, At last, we will conclude our Article with Advantages, Disadvantages, and characteristics of Ferranti effect.
