High-voltage direct current links can transmit electricity across continents with only three percent loss
High-voltage direct current systems transmit electricity across vast distances with just three percent energy loss, outperforming traditional alternating current grids by minimizing the thermal and inductive resistance inherent in long-range power delivery.
High-voltage direct current (HVDC) transformers enable the transport of electricity across entire continents by operating at 800 kV with energy losses as low as 3%, roughly half the loss seen in standard AC systems. These systems utilize modular windings insulated by epoxy-resin composites designed to withstand intense electric fields of 100 kV/mm. To manage the resulting thermal energy, forced-oil cooling systems cycle 10,000 liters of fluid per minute to dissipate 500 kW of heat.
