Electrical Power Transmission and Distribution Systems Explained
Power Transmission and Voltage Optimization
Tension is increased for transport to higher values, up to 400kV, using transformers to reduce transmission losses. This influences the design of high-voltage lines, optimizing costs. Standard transport values include 132kV, 220kV, and 380kV.
Key Electrical Definitions
- High Tension: A three-phase alternating current between phases with 1kV or more at 50Hz.
- Rated Voltage: The normal effective voltage between phases used for line operation.
- Higher Voltage: The maximum effective tension between phases that may occur due to defects or large load disconnections.
- High Voltage Usage: Typically 30kV, 45kV, and 66kV.
