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?

A very strange fault i cam across today,that i never experienced not studied before, i need an answer for this. Phase to phase or line to line , L1,L2 & L3, voltages are 490VAC, but if i use line to ground , its again 490 VAC. . . whats the fault and theory behind of it?
