SSC JE Electrical 39 11Q 22nd Jan Second Shift Machines Hindi - Final 1

महत्वपूर्ण:

द्वि-कुंडली ट्रांसफार्मर की तुलना में एक स्वतंत ट्रांसफार्मर के लाभ:

  • समान VA रेटिंग के लिए अधिक दक्ष
  • आकार में छोटा
  • इनके निर्माण में निम्न ताम्र की आवश्यकता होती है
  • समान VA रेटिंग के दोहरे घुमाव वाले ट्रांसफार्मर की तुलना में लागत कम होती है
  • कोर और ताम्र हानि निम्न प्रतिरोध और रिसाव प्रतिक्रिया के कारण अधिक न्यून होती है जो इसके समकक्ष द्वि-कुंडली ट्रांसफार्मर की तुलना में बेहतर वोल्टेज विनियमन प्रदान करता है
