Add to basketNeuware - Power Line (Feeder) is identified by the voltage of the line. 765, 400, 220, 132, 66, 33, 11 and 0.4 KV lines (feeders) The line of different voltage is according to the load capacity and distance parameters of the power supply. For the same power supply, there is less loss in the high voltage line and more loss in the low voltage line. Line loss is proportional to the square of the current. There are Line interruption (break down) mainly due to phase to earth contact (earth fault), phase to phase contact (over current fault), or both (earth fault and over current fault), and an open circuit fault. Power lines are also particularly affected due to weather (rain, storm, cyclone, flood, arson, incident, movement).Three types of maintenance are done with the view to improve the power supply system 1- Periodic (time bound) maintenance usually twice in a year (post monsoon or before Diwali and second pre monsoon/before monsoon)2 - Corrective Maintenance - Whenever such shortcomings come in the electrical system and they are not rectified in time, then there will be a disturbance in the coming time, so such problems are rectified in advance.3 - Break down (interruption) maintenance - When the power system is interrupted (stopped) due to fault, then the system is regularized only by removing the fault. In the first two repair works, the electrical system is not broken down, but the repair work is done by taking shutdown.

• विद्युत लाइन (फीडर) की पहचान लाइन के वोल्टेज से की जाती है । • विभिन्न वोल्टेज की लाइन विद्युत आपूर्ति के लोड (भार) क्षमता तथा दूरी के मापदंडों के अनुसार होती है । • एक ही पावर की आपूर्ति के लिए अधिक वोल्टेज की लाइन में कम लॉस (हानि) तथा कम वोल्टेज की लाइन में अधिक लॉस (हानि) होते हैं । लाइन लॉस (हानि) करेंट (धारा) के वर्ग (स्क्वायर) समानुपाती होते हैं । • लाइन में होने वाले व्यवधान (ब्रेक डाउन) मुख्यतः फेज के अर्थ (भू-संपर्क) से संपर्क (अर्थ फाल्ट), फेज से फेज के संपर्क (ओवर करेंट फाल्ट), अथवा दोनों (अर्थ फाल्ट और ओवर करेंट फाल्ट) तथा ओपन सर्किट फाल्ट ही के कारण होते हैं । विद्युत लाइन मौसम (वर्षा, आंधी, तूफान, चक्रवात, बाढ़, आगजनी, घटना, आन्दोलन) के कारण भी विशेषत: प्रभावित होती हैं । • विद्युत आपूर्ति व्यवस्था सुधार की दृष्टि से तीन प्रकार के संधारण किए जाते है – • 1- पीरिओडिकमेंटीनेंस/समय बद्ध संधारण – आमतौर पर एक वर्ष में दो बार (मानसून के बाद या दिवाली से पहले और दूसरा प्री मानसून/मानसून से पहले) • 2 – करेक्टिव मेंटीनेंस/सुधारात्माक संधारण – जब कभी विद्युत व्यवस्था में ऐसी कमियाँ आ जाती हैं और समय रहते उनको सुधारा नहीं गया तो आगे आने वाले समय में व्यवधान होगा अत: ऐसे व्यध्यानों को पूर्व से ही सुधार लिया जाता है । • 3 - ब्रैक डाउन मेंटीनेंस/व्यवधान संधारण – जब विद्युत व्यवस्था फाल्ट के कारण बाधित (बंद) हो गई तब फाल्ट को दूर कर/निकालकर ही व्यवस्था नियमित होती है । पहले दोनों सुधार कार्यों में विद्युत व्यवस्था ब्रैक डाउन नहीं होती अपितु शट्डाउन लेकर सुधार कार्य किया जाता है ।
