As of my last update in September 2021, the terms "energization" and "de-energization" in the context of transformers are not common or well-known concepts. Transformers are devices used to transfer electrical energy between two or more circuits through electromagnetic induction, but the terminologies you've mentioned are not part of standard transformer theory or operation.
If you could provide more context or clarify what you mean by "energization" and "de-energization" in relation to transformers, I might be able to assist you further. Otherwise, if you are referring to a different field or topic, please specify, and I'll do my best to provide relevant information.
