What is the function of wave trap in an electrical substation?
Answer Posted / subrata
Wave trap in electrical systems are used for power plant
communication through transmission wires.
It is a combination of low inductance in series and high
capacitance in parallel with transmission wires in power
frequencies. But communication signals are very low amplitude
and very high frequency signals. So, these signals are nearly
open circuited by the inductance and short circuited by the
capacitance.
That is how wave trap power and communication waves and used
in PPC.
