Measuring Current Flow in Open Circuit R Phase

AI Thread Summary
To measure current flow through the neutral wire when phase R is open circuited, a clamp-on ammeter or a current transformer with an ammeter can be used. Calculating the current involves determining the current in each phase and summing them as vectors, considering the 120-degree phase separation in a three-phase circuit. The impedance per load is specified as 3+7j, which is relevant for these calculations. Accurate measurement and calculation are essential for understanding the current distribution in the circuit. Proper techniques ensure effective monitoring of current flow in open circuit conditions.

Measure current using a clamp on ammeter or a current transformer +ammeter.

If you wish to calculate the current, calculate the current in each phase and add them. The currents have to be calculated and added using vectors. Since this is a three phase circuit the currents in the three phases will be 120 degrees apart.

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...
