Znaci na metalnom kucistu jednog uredjaja koji je spojen na  
transformator se osjeti ono kad se rukom prodje kao da vibrira lagano,  
odnosno osjeti se da je na masi neki napon... kako ga izmjeriti?

Hvala

Pa nije trafo nego adapter. Ali je kao od laptopa, veliko kuciste pa  
pretpostavio da je trafo.

Onda pretpostavljam da je masa/nula IZLAZNOG napona preko dva blok  
kondenzatora spojena na fazu i nulu ULAZA!

Tada je napon na toj masi 115Vac ali jako male snage...

A kako moze bit 115Vac ako je adapter 12V 4A... neki mali PC sa  
Celeronom J1900 i 8GB DDR3/32GB SSD i potpuno besumno uletilo za 350 kn  
... dobra cijena... ali i dalje mi nije jasno zasto se osjeti ta  
"vibracija"...

Nije vibracija jer nema pokretnih dijelova

zato sam i stavio navodnike "vibracija"

Kad se dira metalno kuciste kao da vibrira, ali je osjet kao da je  
struja na kucistu.

Hvala, to je odgovor. Nije to nikakvo strasno "peckanje", kad se kuciste  
cvrsto drzi se nista ne osjeca, samo kad se lagano prelazi rukom se  
osjeti. Tako da nema potrebe za uzemljavanjem :)
