What is the network of transformers and transmission cables that transfers electrical power from power stations to consumers called?
A. Distribution Grid B. Transmission Grid C. Power Grid D. Electrical Grid
Answer:
A transmission grid is the network of transformers and transmission cables that transfers electrical power from power stations to consumers.
Electrical transmission is the process of providing highly efficiently generated electricity to a district or over larger and longer distances. The main purpose of the grid is to ensure that people have access to uninterrupted electricity 24 hours a day, especially in populated areas. Transformers play a crucial role in the transmission grid by increasing the voltage to make it more powerful and effective for feasible transmission.
The electrical transmission system includes power plants in cities, distribution systems for easier electricity access, and sub-stations for backup purposes, forming what is known as the electrical grid. This grid meets people's electricity requirements and facilitates the movement of electrical power from its generation to its end use. Since power plants are typically located outside densely populated areas, the transmission system must be large-scale to efficiently distribute electricity.
A transmission grid consists of power stations, transmission lines, and substations, facilitating the bulk movement of electrical energy from generating sites to various locations. The interconnected lines within the transmission grid enable the efficient transport of electrical energy.
Energy is primarily transmitted through the grid using three-phase AC, while single-phase AC is utilized for distribution to end users. Two-phase transmission was previously used but required either a four-wire system or three wires with unequal currents. Higher-order phase systems necessitate more than three wires but may not offer significant benefits.
Overall, the transmission grid plays a crucial role in ensuring the effective distribution of electrical power from power stations to consumers, contributing to the reliable access to electricity for various applications and industries.
