This document establishes a reference software for Rec. ITU-T H.266 | ISO/IEC 23090-3.
NOTE The use of this reference software is not required for making an implementation of an encoder or decoder in conformance to Rec. ITU-T H.266 | ISO/IEC 23090-3. Requirements established in Rec. ITU-T H.266 | ISO/IEC 23090-3 take precedence over the behaviour of the reference software.
High-voltage direct current (HVDC) installations - System tests
IEC 61975:2010+AMD1:2016+AMD2:2022 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 a.c. system. The tests specified in this standard are based on bidirectional and bipolar high-voltage direct current (HVDC) installations which consist of a sending terminal and a receiving terminal, each…
