ultrahøyspente
Ultrahøyspente refers to extremely high voltages, typically those exceeding 300 kilovolts (kV) AC and 400 kV DC. These voltage levels are used in electrical power systems for efficient long-distance transmission of electricity. The primary advantage of transmitting power at such high voltages is the reduction of energy loss due to resistance in the transmission lines. By increasing the voltage, the current required to transmit a given amount of power can be significantly lowered, and power loss is proportional to the square of the current (P_loss = I^2 * R).
The infrastructure for ultrahøyspente systems includes specialized transmission towers, very long and thick conductors, and substations
