  • Cable insulation resistance test (Ispitivanje otpora izolacije kabela)
  • Examination of lightning protection installation (Ispitivanje gromobranske instalacije)
  • Testing of the differential current protective device (DCU) (Ispitivanje zaštitnog uredaja diferencijalne struje (ZUDS))
  • Functional testing of the electrical installation (Funkcionalno ispitivanje elektroinstalacije)
