Answer Posted / durga goud.b

generally wave trap installed where the communication
signal passing. for example it used in the sub station for
power line carrier communication (PLCC) and for
comminication purpose PLCC phones are using without
telephone line. The various frequencies are flows through
the power line and at the same time we are transmitting the
communication signals through it. The power frequency and
PLCC frequencies are difference so, at the ending or
receiving station we are using wave trap to arrest the PLCC
signals to flow through the Power equipements.
