(ps. pisali smo poruku u isto vreme Smile  )

Mjerenje otpora:

- PRIMAR ...     71.7R
- SEKUNDAR ... 2.4R (BLUE BLUE tu se dobijalo 24VAC)
- SEKUNDAR ... 2.6R (YELLOW YELLOW tu se dobijalo 10VAC)

Zaključak? Smile

P.S: Ako uzmem gore navedeni toroid (jer mi dimenzijama savršeno odgovara bez ikakvih modificiranje ili rezanja plastike unutar kucista) zanima me gdje cu da stavim uzemljenje? Sad je sa ovim kineskin transformatorom uzemljenje bilo stavljeno na PCB elektornike jedna zica koja je vodila na LIM EI trafoa i na uzemljenje direkt van na utičnicu 230VAC...pošto toroid ima samo 2 žice na primaru neznam dal da direkt spojim sa PCB elektornike uzemljenje na ulazni konektor 230VC? Jer mi lemna stanica ima ESD (ElectroStatic Discharge) pa da pitam prije kupovine...

Po ovim merenjem trafo izgleda da je uredu jer ti nijedan namotaj nije u prekidu .

Uzemljenje vezujes sa plocice direktno na uticnicu mreznog kabla mozes eventualno ako hoces da se zastitis od strujnog udara sa trafoa da vezes jedan kraj sekundara sa trafoa na uzemljenje.
