Secondary-Side Faults

[edit]

The article states that, "Usually a fault on the secondary side is not a big problem since the conductors will destroy themselves." (emphasis added). I disagree that reliance on conductors to act as fuses is "not a big problem" for an electric power system. Secondary side conductors are typically sized larger than the upstream transformer(s), causing the transformers to act as fuses instead of the conductors. Additionally, the destruction of energized circuit elements typically occurs in spectacular fashion, and often can cause mecahnical or flame-induced damage to nearby circuit elements, which may induce additional faults. Nearby persons or property may also become injured or damaged as a result of such destruction. It is poor engineering practice to rely on a component's failure to isolate a system from faults. The article's wording implicitly endorses this unsafe practice. Moreover, the claim is unsourced and is likey drawn from the original author's own incorrect conclusions.

I have edited the article to clarify the effects of secondary-side faults for spot networks, and I have added a source from the National Renewable Energy Laboratory to support the claim. 144.29.1.26 (talk) 12:58, 24 June 2021 (UTC)[reply]
