Most of the time I see wavetraps on single phases. A wave trap is simply a low pass or band block filter. It is used to block the transmission of carrier waves from propogating beyond where they are desired. Usually these carrier waves are injected onto a single phase for each application, but there is nothing stopping someone from injecting on two or all three, other than the additional cost of injection equipment (additional cost that does not provide much benefit, I might add).
The coupling in three phase lines will cause some of the signal injected on one phase to show up on the other two, but it is usually not enough to justify wave traps on these other phases.
So the answer is it isn't needed.
why three phase induction motor is delta connected
The generated angle between phases in a three phase system is 120 degrees.
A rotary phase converter is commonly used to convert a single phase electrical power source to three phases. This allows you to use three phases instead of one.
In a three phase system, if the current in all three phases are same, then it is a balanced system.
A symmetrical fault is a fault where all three phases are experiencing the same thing. This is also called a three phase fault, since all three phases are involved.
There are three phases of drug effects. These three phases are the administration phase, active phase, and the metabolism phase.
Three phases generated in the United Kingdom should be no different than they are generated anywhere in the industrialized world. Either phase A is followed by phase B followed by phase C, or phase A is followed by phase C followed by phase B
There are actually three phases of swallowing and not two as the question asks. The three phases of swallowing includes: the oral phase, the Pharyngeal Phase, and the Esophageal Phase.
you can't do this. to get single phase from 3 phase you must disconnect 2 of the phases and use one of them as a neutral...b.

Physical phases of matter are not limited to three. Phases of the moon are not limited to three. Phases of a wave form are not limited to three. What phase is limited to three?
The generated angle between phases in a three phase system is 120 degrees.
In a two-phase connection, the phases are displaced by 90 degrees. Two lines (not 'phases') of a three-phase system will provide a single-phase supply, not a two-phase supply.
A rotary phase converter is commonly used to convert a single phase electrical power source to three phases. This allows you to use three phases instead of one.
The three phases of breathing are:The Active phase which is known as (inhalation/ inspiration).Phase 2. gas exchange in the lungs also known as (Internal exchange).The Passive phase which is known as (exhalation /expiration).
The three phases of matter are gas, liquid and solid.
a generator is built in three phases
