Open circuit test & Short circuit test in transformers

Web6 de mar. de 2024 · Jan 12, 2024. #16. For a typical high voltage current transformer for a 500 kV transmission line, current ratio may be 3000:5. If 3000 A flows on the transmission line, 5 A flows on the CT secondary side. If a typical resistor at the CT secondary side is 0.2 ohm, you see 5 A x 0.2 ohm = 1 V on the secondary side. Web1 Answer. Under open circuit test, in a sense, the transformer is no longer a transformer, but a pure inductor. The inductance is proportional to the N^2. So measuring from primary side (higher voltage and higher N in your case), you will see higher inductance, less magnetizing current. From the other side, you will get less inductance and ... banks in sarasota fl https://janradtke.com
