Detailed Solution
Download Solution PDF- इंडक्शन मोटरच्या स्टार-डेल्टा स्टार्टिंग पद्धतीमध्ये, स्टार्ट करताना आणि डेल्टामध्ये सामान्य गतीने चालू असताना स्टेटर विंडिंगला जोडण्यासाठी द्वि-मार्गी स्विचचा वापर केला जातो.
- स्टेटर वाइंडिंग सुरू करताना तारेने जोडलेले असते, त्यामुळे मोटरमधील प्रत्येक टप्प्यावरील व्होल्टेज 1/√3 या घटकाने कमी केले जाईल, जे डेल्टा कनेक्टेड वाइंडिंगसाठी असेल.
- सुरुवातीचा टॉर्क डेल्टा कनेक्टेड वाइंडिंगच्या 1/3 पट असेल.
- म्हणून स्टार-डेल्टा स्टार्टर 1/√3 किंवा 57.73% कमी व्होल्टेजच्या ऑटो-ट्रान्सफॉर्मरच्या समतुल्य आहे.
