Abavelisi kunye nabathengisi beenkqubo zokuvavanya ukuchaneka kweTransformer yangoku esebenzayo yaseTshayina i-Polarity CTPT

Inkqubo yovavanyo lokuchaneka kwe-Polarity CTPT esebenzayo emininzi Umfanekiso obonisiweyo

Inkcazo emfutshane:

Umvavanyi opheleleyo weempawu ze-CTPT sisixhobo sokuvavanya iimpawu ze-PT kunye ne-CT ezenzekelayo ngokupheleleyo. Uvavanyo olunokugcwaliswa sisixhobo luquka: Uvavanyo lweempawu ze-CT volt ampere, uvavanyo lweempawu ze-Pt volt ampere, uvavanyo lwe-CT polarity, uvavanyo lwe-Pt polarity, uvavanyo lwe-CT transformation ratio polarity kunye novavanyo lwe-Pt transformation ratio polarity, ukubala ngokuzenzekelayo i-error curve yayo nayiphi na indawo yomahluko we-CT, CT / Pt transformation ratio kunye nezinye iiparameter zeziphumo,
