Kadaddan Kishin Kashiya ko Genirator da kuma Alternator

Duk fayawa na gida a cikin kwalbar stator yana zama da misali a maimaita masu inganci na generator ko alternator.
Misali a maimaita masu inganci ana amfani a cikin generator tare da amfani da relē masu inganci.

Yanzu relē mai armature mai tsanani suna amfani a wannan abin da saboda suke yi aiki da tsanani da kuma ba su ba sa bi hankali ba game da wata alamun AC na circuit ta kuɗi.

Akwai duwatsuwa uku na transformers mai kwanaki, daya CT an haɓaka a yanar gizo na generator da kuma daya a yanar gaba na generator a kowane fase. Yana da kyau a sani cewa muhimmancin duka transformers mai kwanaki da aka shiga waɗannan fase za su fi dace. Idan akwai wahala mai yawa a cikin muhimmancin transformers mai kwanaki daga baya da karamin generator, zai iya kasance ƙarfafa kan relē masu inganci a lokacin fayawa waje na kwalbar stator da kuma a lokacin aiki na adadin generator. Don haka don haka ya ƙara a yi tasiri na relē ba ta yi aiki idan fayawa na gida ba a cikin yanayin misali a maimaita, an haɓaka resistor a yanar gizo na relē. Wannan tana ƙara cewa idan wata set na CT ta ƙasa, ba za su iya ƙarfafa relē masu inganci ba.

Yana da kyau a amfani da transformers mai kwanaki masu ƙananan don misali a maimaita saboda transformers mai kwanaki masu gaba suna iya ƙara dukar kula na farko zuwa wasu abubuwa masu amfani. Yana da kyau a amfani da duka transformers mai kwanaki don misali a maimaita generators ko alternators suke da muhimmanci daban-daban. Amma a halin ƙarfi akwai wahala mai yawa a cikin muhimmancin transformers mai kwanaki daga baya da karamin generator.

Wannan wahala mai yawa tana ƙara kwanaki mai gajarta a ƙarfin relē. Don haka don haka an samu amfani da biasing na tsari a cikin relē masu inganci.

Relē masu inganci da biasing na tsari yana da duwatsuwa uku na restraint coils da kuma wata operating coil a kowane fase. A cikin relē, torque mai ƙarfin operating coil tana ƙara magana ta relē don ƙarfin trip ta circuit breakers amma a lokacin da torque mai ƙarfin restraint coils tana ƙara magana ta relē saboda torque mai ƙarfin restraint coils tana ƙarfa ne da operating coil. Saboda haka a lokacin fayawa na gaba relē ba za su ƙarfa magana saboda setting ta relē ta ƙara da restraint coils kuma tana ƙara ƙarfafa relē game da kwanaki mai gajarta. Amma a lokacin fayawa na gida a cikin kwalbar stator, torque mai ƙarfin restraint coils ba zai ƙarfa ne kuma relē zai ƙarfa magana idan kula ta setting ta flowing a ƙarfin operating coil.
Setting ta pickup ta current ta masu inganci/bias setting ta relē tana amfani a cikin tsarin tsari mai yawa da ƙara ƙarfi.
Tsari na kwanaki mai gajarta don relē ta ƙarfa magana; tana ƙara da tsari na through fault current tana ƙarfa ita. Wannan tsari tana nufin bias setting ta relē.
