1 DRY TYPE TRANSFORMERS Single-phase, Three-phase/Single-phase, Three-phase/Two-phase,Three-phase 1.1 kv to 7.2kV Class

2 Dry Type Transformers Transformers meant to be installed in a dry and air conditioned room or in a PTI AUGIER type substation. ELECTRICAL CHARACTERISTICS : Power rating and type : Single-phase : TMAI : kva Three-single : TTMAI : kva Three-two : TTBAI : kva Three-phase : TTAI : kva Insulation voltage : 1.1 kv kv kv Primary voltage : Every voltage compatible with insulation voltages above. Usually standard voltages are : 230 V V V V V and 6600 V. Secondary load voltage : 230 V V V V 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

3 CONSTRUCTION : Magnetical circuits with crystal made sheet metal, oriented, with low losses. Copper windings, vacuum impregnated of H class and applying of a fungicide varnish. Metallic flanges. Ironed chassis with rollers. Wooden terminals plate bakelised. Cooling Use Color : in natural air : NA. : use in dry, air conditioned rooms, at a room temperature of -15 C ; + 40 C. : RAL 7035 gray. STANDARDS AND TESTS : Conforms to NF C NF C IEC standards. Other specifications on request. Routine tests U.T.E made on each transformer, specific tests on request..

4 Three-phase dry Type Transformers TTAI ELECTRICAL CHARACTERISTICS : Power rating: kva Insulation voltage : 1.1 kv kv kv Primary voltage : Every voltage compatible with insulation voltages above. Usually standard voltages are : 230 V V V V V and 6600 V. Secondary load voltage : 400 V V V V and 6600 V. Couplings : Step-down Dyn11 - Step-up YNd1, other couplings on request. CONNEXION : Primary and secondary connexions on copper plates, by the upper side of the transformer. STANDARD ACCESSORIES : Voltage tapping adjustable out of voltage : +/- 2,5 % or +- 5% output on slots. Two earthing terminals. Lifting lugs. Four rollers for 10 kva and higher power rating transformers. Naked presentation on frame : IP00. OPTIONAL ACCESSORIES Painted sheet metal enclosure with natural airing upwards, IP21. Connexion on pluggable terminals 3200 V or 5500 V. HRC fuses protection integrated above the protection envelop. Thermal protection by thermal probe integrated to windings, one or two thresholds protection. Tap changers +/- 2,5 % +/- 5%. Keyhole locking of the protection envelop and or pluggable terminals. 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.
