MRCT

Set za ispitivanje relejne zaštite i strujnih transformatora

  • Vodeći u industriji kada je u pitanju trajanje ispitivanja korišćenjem patentiranih merenja sa više otcepa, smanjuje vreme ispitivanja za 20% na strujnim transformatorima sa više otcepa
  • Tačnost koja podržava merenje i klasu zaštite strujnog transformatora
  • Integrisani ispitni sistem jednofazne relejne zaštite
  • Grupisano ispitivanje: demagnetizacija, tačke kolena, odnosi transformacije, krive zasićenja, otpornost namotaja, otpornost izolacije i više
  • Meri sve odnose transformacije i krive zasićenja na strujnim transformatorima sa više otcepa sa jednim ispitnim priključkom
  • Opciono DC tehnika pobude za ispitivanje strujnih transformatora sa tačkama kolena do 30 kV
  • Opciono integrisani VT/CVT ispitni sistem

Megger-ov MRCT je robustan, prenosiv uređaj male težine koji se koristi za sprovođenje demagnetizacije, ispitivanje odnosa transformacije, ispitivanje ulaska u zasićenje, otpornosti namotaja, polariteta, devijacije faza i ispitivanje izolacije na strujnim transformatorima. MRCT automatski izračunava greške odnosa transformacije, krive zasićenja i tačke kolena. MRCT obezbeđuje mikroprocesorski regulisani napon i strujni izlaz, kao i preciznu instrumentaciju za automatsko ispitivanje strujnih transformatora sa jednim i više odnosa transformacije, smanjujući vreme ispitivanja i povećavajući produktivnost. MRCT se direktno povezuje na strujni transformator sa više otcepa i sprovodi sva ispitivanja–ulaska u zasićenje, odnosa transformacije i polariteta, otpornosti namotaja i izolacije–na svim otcepima pritiskom na taster i bez promene ispitnih provodnika.

Instrumentom MRCT se može upravljati preko Megger Smart Touch View Interface (STVI) kontrolera, odnosno LCD ekrana visoke rezolucije osetljivog na dodir koji omogućava korisniku da sprovede manuelno i automatsko ispitivanje brže i lakše korišćenjem ispitnog ekrana, kao i unapred izrađene ispitne rutine. Veliki ekran omogućava korisniku da lako čita sve relevantne podatke tokom sprovođenja ispitivanja i prikaz krive zasićenja strujnog transformatora. Uređaj se takođe može konfigurisati da se isporuči bez Megger STVI i može se upravljati njim pomoću laptop računara sa Megger PowerDB softverom.

Strujni transformatori se mogu ispitivati u konfiguraciji opreme u kojoj su montirani kao na primer ugrađeni u transformatore, uljne prekidače ili razvodne aparature. Neophodno je da oprema bude u potpunosti izolovana od električnog sistema pre sprovođenja ispitivanja.
