Advantages of short circuit and open circuit tests of a
transformer?

Answer Posted / deepak24

1. SCT and OCT are performed to determine Copper and Iron Loss respectively. so by obtaining these values we can obtain efficiency as follows-
efficiency = input/(input+losses)
2. efficiency can be found for any desired load without connecting it to full load.
3. power consumption is less as compare to full load test.
