in case of three phase induction motor,when it is connected
to three phase supply,why the magnetic field is rotets
around the armeture?

Answer Posted / dinesh verma

in indction motor, motor windings also plays a very
important role. these are also placed 120 degree apart. so
when you apply 3 phase supply, it forms a magnetic pole in
the stator. as the 3 phase supply is sinusoidal, the formed
magnetic pole starts rotation in one direction.

In Power Line Communication (PLC) the wave trap is used to block communication signals from entering neighboring lines. My question is this: Why do they allow for different filtering arrangements on these wave traps? Isn't it always going to be a low pass filter since we want the power frequency to go through, and the comm signal blocked?
