Takardunawa na Rukunin Karamin Kirkiyar Zabe

Takardunawa na rukunin karamin kirkiyar zabe tana amfani da hanyoyi daban-daban don in tabbatar da jami'ar karamin kirkiyar zabe a cikin takam da rukuni goma sha'awa, a kan yadda adadin wattmeters da ake amfani da su.

Hanyar Wattmeters Goma Biyu

Yana amfani da wattmeters goma biyu da suka fadada wata rukuni da kuma layi na tsakiya a cikin takam da rukuni goma biyar, don in tabbatar da jami'ar karamin kirkiyar zabe ta kawo addinin karatuwar goma biyu.

Zabubbukan da aka bayyana a cikin takam ya ba da wannan-na

Wannan hanyar tana amfani da shi a cikin takam da rukuni goma biyar. Coil na wattmeters goma biyu suka fadada wata rukuni, masu alama 1, 2, da 3. Coil na pressure suka fadada wata layi na tsakiya. Wannan wattmeter yana tabbatar da zarurfa phase current da line voltage (phase power). Jami'ar karamin kirkiyar zabe tana ba da addinin karatuwar wattmeters goma biyu.

Hanyar Wattmeters Goma Biyu

Yana amfani da wattmeters goma biyu da zai iya amfani da shi a cikin star da kuma delta load connections, ta kawo addinin karatuwar goma biyu don in tabbatar da jami'ar karamin kirkiyar zabe.

Star connection of loads

Idan abincin zai fara da star connected load, zabubbukan ya ba da wannan-na

Don star connected load, karatuwar wattmeter mafi yawan goma biyu tana ba da zarurfa phase current da voltage difference (V2-V3). Duk da haka, karatuwar wattmeter mafi yawan goma biyu tana ba da zarurfa phase current da voltage difference (V2-V3). Saboda haka, jami'ar karamin kirkiyar zabe tana ba da addinin karatuwar wattmeters goma biyu. An za a rubuta mathematically
