Doble LCM500 - Dispozitiv pentru măsurarea curentul de scurgere
Doble LCM500 poate măsura starea unui descărcător în timp ce acesta este încă în funcțiune, măsurând calitatea blocurilor de oxid de metal și contribuind la prevenirea riscului de accidente.
Un descărcător poate să nu fie scump, dar are un rol foarte important in protejarea transformatoarelor.
Cu setul de testare LCM500, este nevoie de mai puțin de 15 minute pentru a stabili dacă descărcătorul funcționează corect și, astfel, transformatorul este în continuare protejat.
