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?

Can any one provide the inspection procedure of MIMIC for VFD panel? Details: If someone wants to have a mimic in the VFD panel what are inputs considered for the mimic(like on,off,trip) whether we are able to add speed variation in the mimic(if so how can we get) and what are the parameters to be checked in the MIMIC during inspection?
