- DC Transmission: Direct Current offers low losses and is more efficient for extensive transmission systems, but converting from AC to DC (and vice versa) involves additional infrastructure.
Types of Ultra-High Voltage Transmission Lines
- AC Transmission Lines: UHV AC lines are advantageous for interconnected, large-scale grid systems where power stability is essential.
- DC Transmission Lines: UHV DC lines are efficient for dedicated long-distance routes with minimal loss.
- Hybrid Lines: Combining AC and DC lines can maximize efficiency across variable distances and terrains.
