Q & A

Why is the transmission system crucial for a country's development?

The transmission system is crucial for a country's development because it facilitates the transfer of electricity from generation stations to bulk consumption centers, which include industries, domestic, and agricultural sectors.

What are the challenges faced in developing high voltage or extra high voltage transmission systems?

Challenges in developing high voltage or extra high voltage transmission systems include minimizing the right of way, protecting flora, fauna, and wildlife, creating high capacity transmission corridors, and ensuring minimal environmental impact.

What is the significance of the right of way in transmission systems?

The right of way refers to the minimum clearance that must be maintained from the mid-point of the tower to either side, which is an important aspect to consider during the construction of transmission lines.

How does the construction of transmission lines impact the environment, particularly flora and fauna?

Transmission lines, especially when constructed over long distances, can cross forests and other natural habitats, potentially affecting flora, fauna, and wildlife. Proper measures must be taken to mitigate these impacts.

What is the role of high capacity transmission corridors in the transmission system?

High capacity transmission corridors play a role in enabling the transfer of power at minimum cost per megawatt and optimizing transmission losses, which is a key reason for adopting UHV transmission systems.

Why is the strengthening of the national grid important?

Strengthening the national grid is important for controlling the entire grid through a single point system, which enhances the stability and reliability of the power supply.

What are the primary functions of insulators in a transmission system?

Insulators in a transmission system serve dual functions: they mechanically support the tower and electrically isolate the conductor from the tower, ensuring the safe transmission of high voltage electricity.

What are the different types of insulators used in transmission systems?

The main types of insulators used in transmission systems are ceramic or porcelain insulators, glass insulators, and more recently, polymer composite or silicon rubber insulators.

Why are conductors important in a transmission system?

Conductors are important in a transmission system as they transmit high voltage electricity over long distances from generating stations to the transmission system.

What are the key components of a transmission tower?

Key components of a transmission tower include insulators, conductors, the tower structure itself, foundation, earth wire or ground wire, hardware fittings, and various accessories.

How do environmental factors like temperature and UV radiation affect insulators?

Environmental factors such as temperature fluctuations and UV radiation can cause thermal expansion and contraction in insulators, potentially leading to mechanical stress. UV radiation can also degrade the surface of insulators, especially polymer types, affecting their hydrophobicity and longevity.
