Idéal pour
Non recommandé pour
Pour le TC : Connecter l'enroulement primaire en série avec la ligne. Les bornes secondaires sont 1S1 et 1S2 pour l'enroulement principal ; si un enroulement de protection existe, utiliser 2S1-2S2. Ne jamais ouvrir le circuit secondaire d'un TC sous tension - tension dangereuse. Mettre à la terre l'enroulement secondaire en un seul point. Respecter IEC 61869 / GB/T 20840 pour le repérage des bornes et la sécurité. ⚠️ Safety: Follow the nameplate terminal diagram and ground the secondary winding at one point.
Conforme à : IEC 61869 / GB/T 20840
