“Short Circuit Test & Open Circuit Test of a Transformer

Описание: ⚡ Short Circuit Test & Open Circuit Test of Transformer | Core Loss & Copper Loss Explained ⚡
In this video, we explain the Short Circuit Test and Open Circuit Test of a Transformer in a clear, conceptual, and exam-oriented manner. These two tests are fundamental experiments in electrical engineering used to determine core (iron) loss, copper loss, transformer efficiency, and equivalent circuit parameters without loading the transformer fully.
The Open Circuit Test (No-Load Test) is performed to evaluate core loss and no-load current, while the Short Circuit Test is conducted to calculate copper loss and full-load efficiency using a low applied voltage and high current condition. Together, these tests play a crucial role in transformer performance analysis and are widely asked in GATE, university exams, and technical interviews.
This video is especially useful for:
✔ Electrical Engineering students
✔ GATE & competitive exam aspirants
✔ Diploma & B.Tech learners
✔ Anyone studying Electrical Machines & Power Systems
📌 Topics covered in this video:
• Open Circuit Test of Transformer
