Homework Help Overview

The discussion revolves around understanding transformer taps and the rated voltages of transformers, specifically a 200/480 V transformer. Participants are trying to clarify the meaning of '13' in the context of transformer voltage ratings.

Discussion Character

  • Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • Participants are questioning the interpretation of the voltage ratings and the significance of the number '13'. There is also a discussion about the nature of distribution transformers and their typical configurations.

Discussion Status

Some participants have offered corrections regarding the voltage, suggesting it should be 13200 V instead of 200. There is acknowledgment of potential confusion due to fatigue, indicating a reflective and exploratory nature in the discussion.

Contextual Notes

Participants mention the context of distribution transformers and their common use cases, hinting at practical applications and assumptions about transformer types.

In the question below i know 200/480 V is rated voltage at primary and secondary side of a transformer, but '13' is what i do not know. Also how does the solution work out? i have tried every possible thing. Thanks(Sorry if i could not phrase my question in accordance to the pattern)

It is not 13, 200 but 13200 V

omg! what was i thinking. Lack of sleep yesterday night may be causing this weird behavior .

Possibly:wink:.
I often make ridiculous arithmatic mistakes when I am sleep-deprived.

In practice, distribution transformers are always step-down transformers, so you won't find any 200/480 transformer.
 
I had good use for a 110 -> 220V transformer while living in a developing country...
But I grant that the nameplate didn't say 'distribution transformer':smile:
