I have just familiarized with the notion of inductive kick from inductors due to switching out a path to ground.
However, I am not entirely sure about the effect we would see from transformers because in effect its primarily an inductor. With respect to transformers with the following sequence of events:
1) Voltage source connected to primary and load connected on the secondary (i.e. normal operation).
2) Load on secondary is opened or removed (similar setup as an open circuit test for transformers).
Would there be an inductive kick from the transformer causing a voltage spike on the secondary open circuit terminals even though there is some minimal current flowing through the primary terminals? If so, how large of a spike will it be relative to the existing secondary voltage? Will it continue to increase until an arc is formed across the secondary open circuit terminals? Is there a possibility of the core saturating?
My guess is there will be a voltage spike due to the change in current, but I can't be sure since there is a path to ground for the current to flow from the inductor.
Any help on this matter would be much appreciated.
