Thyristor valves for thyristor controlled series capacitors (TCSC) - Electrical testing
IEC 62823:2015 defines routine and type tests on thyristor valves used in thyristor controlled series capacitor (TCSC) installations for a.c. power transmission. The tests specified in this standard are based on air insulated valves operating in capacitive boost mode or bypass mode.
Thyristorventile für thyristorgesteuerte Reihenkondensatoren (TCSC) - Elektrische Prüfung
Valves à thyristors pour condensateurs série commandés par thyristors (CSCT) - Essai électrique
L'IEC 62823:2015 définit les essais individuels de série et les essais de type sur les valves à thyristors utilisées dans les installations de condensateurs série commandés par thyristors (CSCT) pour transmission de puissance en courant alternatif. Les essais spécifiés dans la présente Norme sont basés sur des valves isolées par l'air fonctionnant en mode capacitif amplifié ou en mode de shuntage.
Tiristorski ventili (elektronke) za zaporedne kondenzatorje s tiristorskim upravljanjem (TCSC) - Električno preskušanje
Ta mednarodni standard opredeljuje rutinske in tipske preskuse za tiristorske ventile v inštalacijah zaporednih kondenzatorjev s tiristorskim upravljanjem (TCSC) za prenos izmenične električne energije. Preskusi, navedeni v tem mednarodnem standardu, temeljijo na zračno izoliranih ventilih, ki delujejo v načinu kapacitivnega pospeševanja ali obvoda. Pri drugih vrstah ventilov in pri ventilih, ki delujejo v načinu induktivnega pospeševanja, se naročnik in dobavitelj sama dogovorita o zahtevah za preskuse in merilih sprejemljivosti.
