Transformers

Three-Phase Transformer

Just as single-phased transformers, three-phased transformers are used to adapt voltage ot three-phased lines.

Various kinds of connection are available (delta-connected or Y-connected circuits), and multi-phase secondary windings can be created.

Applications :

-    General purpose (voltage adaptation, etc…)
-    Autotransformer
-    Industrial frequency
-    Railways frequency
-    Military frequency

Electrical characteristics  :

-    Power : up to 100 kVA (higher power on request)
-    Voltage : up to 1000V (higher voltage -> please refer to High voltage transformers)
-    Insulation voltage : up to 5kV DC (higher voltage -> please refer to Insulation transformers)
-    Current : up to 500A
-    Frequencies :
•    Industrial : 50Hz and 60Hz
•    Railways : 16 2/3 Hz and 50Hz
•    Military : 400Hz

Terminals :

-    Screw terminals
-    Protected terminals
-    High voltage insulated terminals
-    Flat tags or U terminals
-    Pins for P.C.B.
-    Connectors

Standard design :

-    Bare
-    Encased
-    Safety casing
-    Resin moulding : epoxy, polyurethane, silicone, loaded resins (resins may be requested in accordance with the standard UL 94 V0, fire smoke, etc…)
-    Other casing on request
