Because DC electricity has no frequency, it''s not as affected by the corona discharge, and it''s therefore not necessary to bundle conductors together in high-voltage DC transmission systems. When it''s not necessary to bundle conductors together, less conductor material is necessary, which results in a less expensive infrastructure for HVDC systems with

DC voltage could not be transformed, meaning that energy could not be transmitted long-distance without high voltage drop values and power losses. Thomas Alva Edison and his team developed the DC generator, circuit breaker equipment, fuses, bulbs, and the first DC systems in 1881.
Abstract. HVDC transmission line designs are in many respects similar to those of high voltage AC transmission lines. The key differences are that most HVDC lines are connected to bipolar converters and therefore, use only two pole conductors; one for the positive pole and the other for the negative pole. Some lines, however, include a

HVDC transmission systems use DC mode to transform and transmit power with high voltage and large capacity. HVDC is usually composed of a rectifier that converts AC to DC voltage, a high-voltage DC transmission line, and an inverter that converts DC to AC.
