What is the difference between phase current & line
current, how both can be measured in star and delta system
Answer Posted / mani
The phase current is current flow between phase to neutral
is called phase current and the line current is current
flow between two phases is called line current.
In Star winding entire line current passes thru
individual phase i.e. I(ph)=I(L)
In Delta winding however line current gets divided in two
windings. Here I(ph)=I(L)/1.732. Here 1.732 is square root
of 3.

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?
