Napon primara, Primary voltage: 400 V, 50 Hz

Napon sekundara, Secondary  voltage: 12 V, 50 Hz

Snaga jezgra, Core power: 4,5 kW

Presek jezgra, Core cross section: 65 x 105 mm

Struja primara pod opterećenjem, Primary current under load: 17 A

Struja na sekundaru nije merena a žica je, Secondary wire cross section:  90 mm2.

Žica na primaru je prečnika, Primary wire round, diameter:   2,12 mm.

kad se iskvadrira jezgra dobije se 0,65 zavoja po 1 voltu

Quadraturing core we get 0,65 turns per 1 volt,

0,65 x 400 v = 260 zavoja u primaru, number of turns in the primary winding.

a u sekundaru:

Number of turns in the secondary winding

0,65*12 v = 7,8zavoja, turns.

Transformer is designed to work with higher induction in Tesla.

transformator je projektovan da radi sa većom indukcijom
