Step down transformers used in residential AC Mains distribution

AI Thread Summary
In a residential distribution system, a pole top mounted step down transformer reduces high primary voltage to a lower secondary voltage for safe use. If the primary side voltage increases, the secondary voltage also increases proportionally, maintaining the transformer's voltage ratio. However, the extent of the increase in secondary voltage depends on the degree of the primary voltage rise. This relationship is crucial for understanding transformer behavior in residential AC mains distribution. Proper transformer design ensures that voltage fluctuations on the primary side do not lead to unsafe conditions on the secondary side.

TL;DR Summary
When the voltage rises on the primary what happens to the secondary?
Hello,

If we have a pole top mounted distribution step down transformer for residential use what happens to the voltage on the secondary side if the primary side voltage increase?

Thank you

It increases proportionally.

I guess it depends on how much that primary side voltage increases... :wink:

Thread 'Weird near-field phenomenon I get in my EM simulation'

I recently made a basic simulation of wire antennas and I am not sure if the near field in my simulation is modeled correctly. One of the things that worry me is the fact that sometimes I see in my simulation "movements" in the near field that seems to be faster than the speed of wave propagation I defined (the speed of light in the simulation). Specifically I see "nodes" of low amplitude in the E field that are quickly "emitted" from the antenna and then slow down as they approach the far...

Thread 'EMF (Electromagnetic Field) & EHS (Electromagnetic Hyper Sensitivity)'

Hello dear reader, a brief introduction: Some 4 years ago someone started developing health related issues, apparently due to exposure to RF & ELF related frequencies and/or fields (Magnetic). This is currently becoming known as EHS. (Electromagnetic hypersensitivity is a claimed sensitivity to electromagnetic fields, to which adverse symptoms are attributed.) She experiences a deep burning sensation throughout her entire body, leaving her in pain and exhausted after a pulse has occurred...
