M.C.B( Mini circuit breaker )- मिनी सर्किट ब्रेकर -किया होता है

 आधुनिक समय में फ्यूज का स्थान एम.सी.बी ने ले लिया है । एम सी बी का प्रयोग काफी अधिक बढ़ गया है क्योंकि -
  • एम.सी.बी इसकी स्थापना अत्यधिक सरल तथा सुन्दर होती है ।
  • एम.सी.बी अधिक भरोसेमन्द है ।
  • एम.सी.बी शोर रहित और धुंआ रहित है ।
  • एम.सी.बी को देखभाल की आवश्यकता नहीं होती है ।
  • एम.सी.बी में करंट लगने का डर नहीं होता । दोष पड़ने पर संचालित करना बेहद सरल है । दोष दूर करने पर केवल स्विच की नॉब को ऊपर उठाना होता है ।
  • तुरन्त ऑपरेट हो जाता है । ये ओवरलोड करंट के चौथे भाग पर ही परिपथ काट देता है ।
  • एम.सी.बी की स्थिति देखकर ही दोष वाले सर्किट का पता लगाया जा सकता है ।

Duality of Thevenin and Norton theorem

Duality of Thevenin and Norton theorem In electrical network analysis system, electrical terms are associated into pairs called duals. So,hereby you should know the relationship in between Thevenin's and Norton theorem. As we know that; Thevenin’s theorem simplifies calculations and explanations of complex circuit operations. Norton’s theorem also simplifies complex circuits.  In both of the theorem the ultimate objective is to simplify complex circuit. But, observe the twist: to find the Norton current we have to place a direct wire connection between the open load resistance points or directly shorted it and determine the resultant current, this step is exactly opposite the respective step in Thevenin’s Theorem, where we replaced the load resistor with a break (open circuit). The current through a component or voltage across the element present in the branch network is determined using Norton and Thevenin's theorem respectively. So ,we can say that they both are...

E.L.C.B( Earth leakage circuit breaker) - ई.एल.सी.बी. का पूरा नाम अर्थ लीकेज सर्किट ब्रेकर है

ई.एल.सी.बी अर्थ लीकेज की स्थित पर सर्किट को सप्लाई से अलग करके न केवल मनुष्य को करंट लगने से बचाता बल्कि सर्किट को सुरक्षा भी प्रदान करता है । यह अत्यंत लाभकारी है ।

Electrical Power Substation Engineering and Layout Electrical Substation Step Up Substation Step Down Substation Primary Step Down Substation Secondary Step Down Substation Distribution Substation Bulk Supply or Industrial Substation Mining Substation Mobile Substation Outdoor Type Substation Indoor Substation Underground Substation Pole Mounted Substation Electrical Substation Now days the   electrical power   demand is increasing very rapidly. For fulfilling these huge power demands the modern time requires creation of bigger and bigger power generating stations. These power generating stations may be hydro – electric, thermal or atomic. Depending upon the availability of resources these stations are constructed different places. These places may not be nearer to load centers where the actual consumption of power takes place. So it is necessary to transmit these huge power blocks from generating station to their load centers. Long and high   voltage   tran...
