 HVAC for High voltage direct Current (HVDC) Courtesy ABB High - volt age , direct current ( H VD C ) is an electrical transmission technology that uses direct current ( DC ) volt ages greater than the nominal system voltage in order to increase power transfer capacity . The higher volt ages allow for more efficient transmission of electrical power over long distances . A high-voltage, direct current ( HVDC ) electric power transmission system uses direct current (DC) for the bulk transmission of electrical power An H VD C is situated in a Far aday cage used to protect electronic equipment from high voltage direct current ( H VD C ) electromagnetic fields . The cage surrounds the equipment and prevents the H VD C fields from reaching it . The cage is made of conduct ive material , such as metal , and is typically grounded .
