AI Thread Summary
To calculate the terminal voltage of two single-phase transformers in parallel with a load impedance of (0.25 + j0.1), one must first determine the load current contributed by the impedance. The circulating current at no load has been calculated, but the next step involves analyzing the load's effect on the system. Using the provided transformer parameters, including rated currents, resistances, and reactances, will help in this calculation. The method suggested involves complex impedance analysis, which is essential due to the nature of transformers. Ultimately, accurate terminal voltage calculation requires careful consideration of both transformers' contributions under load conditions.

Hello,
Suppose 2 single phase transformers have the following:

T1 T2
Rated Current 200A 600A
Resistance(pu) 0.02 0.025
Reactance(pu) 0.05 0.06
No-Load emf 245V 240V

What is the terminal Voltage when they are connected in parallel and supplied a load impedance of (0.25 + j0.1).

----------------------------------------------
What I've done.
I've calculated the circulating current when there is no load. But I do not know what current will be contributed by the load impedance. What should I do ?

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...
