when i am going to take trail on a 3ph sq.i/m motor 5.5kw,
i observed that RPM of the motor is very low as compared to
the rated RPM and also it rotates in clockwise in first ON
command,and anticlock wise in second ON command.
finally i observed that on phase is no available .
but iam not clear about, why the motor is rotates in both
directions without any phase interchanging.pls answer to my
question.

In Power Line Communication (PLC) the wave trap is used to block communication signals from entering neighboring lines.
