Litaba - PT/CT ke eng?

PThangata e tsejoa e le voltage transformer indastering ea matla 'me CT ke lebitso le tloaelehileng la transfoma ea hajoale indastering ea matla.

Voltage transformer (PT): ke sesebelisoa sa motlakase se fetolang motlakase o phahameng oa sistimi hore e be motlakase o itseng o tlase (100V kapa 100 / √ 3V).

Potential transformer (PT, VT) e tšoana le transformer, e sebelisetsoang ho fetola motlakase moleng.Leha ho le joalo, morero oa hore transformer e fetole motlakase ke ho fetisa matla a motlakase.Bophahamo bo boholo haholo, hangata ka kilovolti ampere kapa megavolt ampere joalo ka yuniti ea lipalo.Morero oa hore motlakase o fetole motlakase o sebelisoa haholo ho lekanya limithara le phepelo ea motlakase ka lisebelisoa tsa ts'ireletso ea relay, ho lekanya motlakase, matla le matla a motlakase a mohala, kapa ho sireletsa lisebelisoa tsa bohlokoa moleng ha mohala o hloleha. motlakase transformer e nyenyane haholo, ka kakaretso ke volt ampere tse seng kae feela, tse ngata tsa volt ampere, 'me boholo ba eona ha bo fetang sekete sa volt ampere.

Transformer (CT) ea hajoale: ke sesebelisoa sa motlakase se fetolang matla a teng tsamaisong ea motlakase o phahameng kapa motlakase o moholo oa sistimi ea motlakase o tlase hore e be motlakase o itseng o monyane (5a kapa 1a).
