Nicely explain keep making such videos
Good đ
Gyaan bhai, thoda Knee point theory ko BH curve se relate karke explain kijiye na...
Nice explainâ¤
Hello! As we see we connect our ac voltage source direct at secondary winding and we measure the current also on the secondary winding with ammeter. In this case we donât have transformation of the voltage level so the magnetic core donât interfere! But again we observe the saturation phenomenon. In my mind the proper procedure was to connect our supply on the primary winding and observe(measure) the secondary. Now i am thinking itâs like we power an individual resistance and measuring the current through it. Can you explain me why we still we reach to saturation whilst voltage level between primary and secondary donât change? I hope you understand my concern!
0.2 amp. se 0.3 amp. current already 50% increase kr rha he sir. 20 v se 40 v increase krne pr sir. Knee Voltage to fir 40V hi ho gya.

In my case, when i give suppy voltage to secondary, it behave as a short circuit and high current flows in secondary even with low voltage. Then how can i perform this test with 200:5 ct or 5:1 ct ?
How we calculate primary current or secondry current upto the knee point, which is accurate upto the knee point ,and further the knee point the current is inaccurate
what is differnence between VK and VK/2. we have to perform test at VK or VK/2?. if suppose 200 is VK and VK/2 is 100. then we to do at 10%,40%... 100% , 110% of 100?
