High-voltage direct current (HVDC) installations. System tests1 Scope This International Standard applies to system tests for high voltage direct current (HVDC) installations which consist of a sending terminal and a receiving terminal, each connected to an AC system. The tests specified in this standard are based on bidirectional monopolar and bipolar high voltage direct current (HVDC) installations which consist of a sending terminal and a receiving terminal, each connected to an AC system. The test
