Flywheel energy storage (FES) works by accelerating a rotor (flywheel) to a very high speed and maintaining the energy in the system as rotational energy. When energy is extracted from the system, the flywheel's rotational speed is reduced as a consequence of the principle of conservation of energy; adding. .
A typical system consists of a flywheel supported by connected to a . The flywheel and. .

The substation may include the following equipment: 1. Power transformer or distribution transformer (depending on substation type) 2. Circuit breakers 3. Disconnecting switches 4. Isolators 5. Busbars 6. Current transformers 7. Potential transformers 8. Lightening arrestor 9. Protective relays 10.. .
Transformers are an essential part of any electrical power system. They come in various sizes and voltage ratings. AC transformers are one. .
Circuit breakers which control high voltages and protect other substation equipment are also located at power substations. Many outdoor substations use oil-filled circuit. .
The electrical and physical connection of substation buses are typically governed by safety, reliability, economy, maintainability and ease of operations. Bus is actually the electrical structure to which all power lines and transformers are connected. Generally, there are. .
Disconnecting switches are used to disconnect electrical equipment from the power lines which supply the equipment. Ordinarily, disconnect switches are not operated when. .
Substations typically serve at least one of the following purposes: • Increasing the voltage produced by for efficient over long distances, using step-up transformers • of different power grids
