AI Thread Summary
An autotransformer can effectively start a 5000hp motor with an 11kV voltage rating by utilizing its tap ratings of 50%, 65%, and 80%. The starting method depends on the motor's load and torque-rpm characteristics, which influence the required voltage and current during startup. The autotransformer reduces the initial voltage supplied to the motor, allowing for a smoother start and minimizing inrush current. This approach helps in protecting the motor and associated equipment from damage due to high starting currents. Understanding the specific application and motor characteristics is crucial for optimal autotransformer use as a starter.

Thread '3-terminal device external modeling'

Very basic question. Consider a 3-terminal device with terminals say A,B,C. Kirchhoff Current Law (KCL) and Kirchhoff Voltage Law (KVL) establish two relationships between the 3 currents entering the terminals and the 3 terminal's voltage pairs respectively. So we have 2 equations in 6 unknowns. To proceed further we need two more (independent) equations in order to solve the circuit the 3-terminal device is connected to (basically one treats such a device as an unbalanced two-port...

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...
