Question
what is Wave Trap? And its Function ? Detail? Where it is Used?
 Question Submitted By :: Electrical-Engineering
I also faced this Question!!     Answer Posted By  
 
Answer
# 1
Line trap also is known as Wave trap. What it does is
trapping the high frequency communication signals sent on
the line from the remote substation and diverting them to
the telecom/teleportation panel in the substation control
room (through coupling capacitor and LMU).
This is relevant in Power Line Carrier Communication (PLCC)
systems for communication among various substations without
dependence on the telecom company network. The signals are
primarily teleportation signals and in addition, voice and
data communication signals. Line trap also is known as Wave
trap. What it does is trapping the high frequency
communication signals sent on the line from the remote
substation and diverting them to the telecom/teleportation
panel in the substation control room (through coupling
capacitor and LMU).
This is relevant in Power Line Carrier Communication (PLCC)
systems for communication among various substations without
dependence on the telecom company network. The signals are
primarily teleportation signals and in addition, voice and
data communication signals.

The Line trap offers high impedance to the high frequency
communication signals thus obstructs the flow of these
signals in to the substation busbars. If there were not to
be there, then signal loss is more and communication will
be ineffective/probably impossible.

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.

wave trap is a plcc communication in power system which
block the outer frequeny of other power station these are
installed in switch yard i was seen wave trap in
gandhinagar thermal power station and i remember it

Dear Sirs, I am a technical persons.In one of our Electrical Sub- Station, We have installed three numbers of 1250KVA ,11KV/0.415KV Transformer to feed the Factory load. We have found some abnormality. In one of our Transformers the leakeage current from transformer body to earth through earth continuity wire is almost 86 Amp but in other transformer it is (5-10)Amp. where the load current on three phase and neutral are respectively 1360Amp,1400Amp,1370 Amp & 176Amp. So please any technical person help me about the reasons of this situation and how I can rectify the fault. Moreover,I have measured the earth resistance of the Earth continuity wire which is less than 1 Ohm. Thanks Tapas Barua   2
