Three phase transformers are used on three phase energy systems either as security - isolation type transformer or step up -down transformer, in some cases step-up and step down transformers can be produces as auto transformer for reducing the price.
Nominal Power
• Isolation type or auto type
• Input-output voltage and current values according to duty factor
• Input - output connection types ( delta - star etc )
• Galvanic isolation
• Input - Output voltage steps
• Input-output connection materials
• Isolation class
• Metal enclosure and ventilation
• Mounting type ( horizontal - vertical ) ... etc
OMSAN determines these technical specifications by communicating directly to the customer before designing process in order to avoid any problem. When every detail is clear a sample transformer is produced and tested by OMSAN and submitted to the customer for the final approving before the ordering.
