ELECTRICAL CHARACTERISTICS : Power rating and type : Single-phase : TMAI : 5-7.5-10 - 16-25 - 32-50 kva Three-single : TTMAI : 16-25 - 32-50 - 63-80 - 100-125 - 160 kva Three-two : TTBAI : 16-25 - 32-50 - 63-80 - 100-125 - 160 kva Three-phase : TTAI : 16-25 - 32-50 - 63-80 - 100-125 - 160-200 250-400 - 500-630 kva Insulation voltage : 1.1 kv - 3.6 kv - 7.2 kv Primary voltage : Every voltage compatible with insulation voltages above. Usually standard voltages are : 230 V - 400 V - 950 V - 3200 V - 5500 V and 6600 V. Secondary load voltage : 230 V - 400 V - 950 V - 3200 V - 5500 V and 6600 V. Couplings : Standard : Three-phase transformer : Step-down Dyn11 - Step-up YNd1 single-phase transformer :Ii0 Specific : Three-single transformer, Leblanc three-two transformer, other couplings on request. Manufacturing specifications on request : Inrush current transformer reduced or very reduced. CONNEXION: Primary and secondary connesion on copper slots, by the upper side of the transformer. STANDARD ACCESSORIES : Empty setting plugs : Three outputs on slots. Two earthing switches. Lifting lugs. Four rollers for 10 kva and higher power rating transformers. NOTE : Transformers mechanical and electrical characteristics are the same for step-down or step-up transformers. The tranformers are not reversible. Step-up transfrormers are built so that inrush currents are limited. Single-phase transformer, TMAI type, with IP21 encolsure, fuse terminal 3200 V and locking. 2
