Question about balanced wye - delta connection

AI Thread Summary
To determine line currents in a balanced wye-delta connection with line impedance, it is essential to convert the delta load to a wye configuration first. Directly adding line impedance to the delta load without conversion is not advisable. After converting to wye, calculate the line currents, then revert to the delta configuration for further analysis. This method simplifies the calculations and ensures accuracy in determining both line and phase currents. Proper conversion is key to solving these types of electrical problems effectively.

i am confused on how to find the line currents when there is a line impedance in between the wye source and delta load... is it wrong to directly add the line impedance and the delta load without converting first the delta load to wye...? is there a way that i can find the line currents and phase currents...i know i cannot directly find the phase current on the delta load since there is a line impedance...plese help i am really having trouble on how to solve this kind of problem. Thank you in advance...

Hi
Simplest way to solve it ? convert delta (D) load to wye (Y) and then calculate line currents. Then go back to delta.

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...
