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?

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 don’t have transformation of the voltage level so the magnetic core don’t 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 it’s 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 don’t change? I hope you understand my concern!
