High-voltage direct current (HVDC) transmission - Vocabulary
IEC 6033:2019 defines terms for high-voltage direct current (HVDC) power transmission systems and for HVDC substations using electronic power converters for the conversion from AC to DC or vice versa. This document is applicable to HVDC substations with line commutated converters, most commonly based on three-phase bridge (double way) connections (see Figure 2) in which unidirectional electronic…

IEC 61158-4-4:2019 La couche de liaison de données assure les communications de messagerie à contrainte de temps de base entre les appareils d'un environnement d'automatisation.
Ce protocole fournit un moyen de connecter des appareils par le biais d'un réseau maillé partiel, de sorte que la plupart des défaillances d'une interconnexion entre deux appareils peuvent être…
Extended thermal cycling of PV modules - Test procedure
IEC 62892:2019 defines a test sequence that extends the thermal cycling test of IEC 61215-2. It is intended to differentiate PV modules with improved durability to thermal cycling and evaluate modules for deployment in locations most susceptible to thermal cycling type stress. This document is based on the ability for 95 % of the modules represented by the samples submitted for this test to pass…
