# Commission Regulation (EU) 2016/1447 of 26 August 2016 establishing a network code on requirements for grid connection of high voltage direct current systems and direct current-connected power park modules (Text with EEA relevance), Article 19: Short circuit contribution during faults

Extent: E+W+S+N.I.

1. If specified by the relevant system operator, in coordination with the relevant TSO, an HVDC system shall have the capability to provide fast fault current at a connection point in case of symmetrical (3-phase) faults.
2. Where an HVDC system is required to have the capability referred to in paragraph 1, the relevant system operator, in coordination with the relevant TSO, shall specify the following:
(a) how and when a voltage deviation is to be determined as well as the end of the voltage deviation;
(b) the characteristics of the fast fault current;
(c) the timing and accuracy of the fast fault current, which may include several stages.
3. The relevant system operator, in coordination the relevant TSO, may specify a requirement for asymmetrical current injection in the case of asymmetrical (1-phase or 2-phase) faults.
