Detailed Solution
Download Solution PDFत्रि-प्रावस्था भारमध्ये, तीन भिन्न संरोध तारका किंवा डेल्टा पद्धतीने एकत्र जोडले जातात.
त्रि-प्रावस्था प्रणालीमध्ये डेल्टा वळणाच्या एका टोकाला दुसऱ्या वळणाच्या सुरुवातीच्या टोकाशी जोडून तयार होतो आणि बंद लूप तयार करण्यासाठी जोडणी चालू ठेवली जाते.
त्रि-प्रावस्था प्रणालीमध्येमधील तारा तिन्ही संरोधांपैकी एका टोकाला जोडून तयार होतो.
महत्वाचे मुद्दे:
तारका-जोडणी केलेल्या त्रि-प्रावस्था प्रणालीमध्ये,
VL = √3 × Vph
आणि IL = Iph
\({I_{ph}} = \frac{{{V_L}}}{{\surd 3Z}}\)
डेल्टा जोडणी केलेल्या त्रि-प्रावस्था प्रणालीमध्ये,
VL = Vph
IL = √3 × Iph
\({I_{ph}} = \;\frac{{{V_L}}}{Z}\)
जिथे,
VL तार व्होल्टता आहे
Vph प्रावस्था व्होल्टता आहे
IL तारमार्ग विद्युतप्रवाह आहे
Iph प्रावस्था विद्युतप्रवाह आहेLast updated on Jun 11, 2025
