tester pentru curent trifazic

ma intereseaza daca are cineva o schema pentru un aparat cu doua leduri care sa indice sensul in care se invarte mororul intr-o anumita configuratie a fazelor, am gasit ceva de cumparat de-a gata, dar mi se pare enorm sa dau 60 de euro pe o jucarie cu doua leduri

cred ca e vorba de becuri indicatoare cu neon(ca alea din intrerupatoare),nu de tuburicred ca se pot inlocui cu leduri(alimentate printr-o punte si o rezstenta adecvata)

da, la asta nu m-am gandit, nu e obligatoriu sa fie leduri, imi voi face de lucru zilele astea cu respectiva schema, multumesc, totusi ce ma nelamureste e faptul ca ambele neoane sunt notate cu NE2 si rezistentele de 10w

...totusi ce ma nelamureste e faptul ca ambele neoane sunt notate cu NE2...

Ambele becuri cu neon sunt de tip NE-2, notatia nu se refera la referinte ci la tipul componentelor.
