In planta es común escuchar:
“It’s electrical noise.”
However, we can explain what it means to repeat the phrase.
No es brujería, no es mala suerte…
It is physical and, therefore, all of them have been accumulated.
- Induction: potential to contaminate signals
If you have power cables and signal cables attached to each other, the problem is firm.
The power induces voltages which do not cause any damage.
Tips:
Sensors that change reading without motivation.
Variators with erratic behavior.
PLCs detect fantasy signals.
The induction is a silent enemy… and easy to avoid if it separates from the roads.
- Harmonics: the distortion that your system sends
VFDs, switched sources and non-linear loads distort the direction.
This “ruido” ended affecting all that toca.
What is provocative:
Transformers are calentándose without explanation.
Sensitive instruments with unstable readings.
Intermittent failures that appear to be random.
The harmonicas do not happen, but they do not sound like they are playing.
- The door to the ground: the point that all must hold well
All we say is “sí, sí, ya tiene tierra”…
The next big thing is: Is there just one reference where the veins are poorly distributed?
There may be a third generation of potential differences that are directed to your signals.
Y luego culpan al PLC.
- Bad blinds: protection… from adornment
The cable can be shielded, but if:
the blind is cut,
it was landed without death,
o lo dejaron “ahí nomás”…
Entonces no sirve.
When the noise disappears, the almacena.
A term… pero de interference.
The electrical noise has a number and a call.
No es un misterio nor un místico fenómeno.
Is the result of:
Popular design
Improvised installation
Reactive maintenance
Wrongly selected or incorrectly selected equipment
When you plant “you see where you are”
If you:
signals that there is nothing wrong with it,
readings that do not coincide,
variadores actuando as if you have life propia…
No es karma industrial.
It is electrical noise. There you have the solution.
