INDUSTRIAL TRANSFORMERS

Tesar manufactures industrial transformers since 1979. The industrial transformers Tesar are the result of a precise work based on continuous research and development
Technichal characteristics of industrial transformers
TAP CHANGER
Usually the primary windings are fitted with a 5 position tap changer +-2 x 2.5%. Other values are available on request.
Vectorial group
The standard vectorial group of the industral transformers is Dyn11. Other vector groups are available on request.
Temperature rise
The ambient temperature usually doesn't exceed 40°C and the standard industrial transformer has temperature rise of the windings not exceeding 100 K. Tesar transformers can be designed for installation in places with higher ambient temperature up to 55° C.
Sound pressure
Tesar distribution industrial transformers have very low sound pressure levels, from 48 up to 66 db (A)
Installation altitude
The maximum installation altitude of our standard industrial transformers is 1000 m above the sea level. Anyway we can manufacture industrial transformers for higher installation altitudes.
