This is for a specific scenario.
Sometimes when a high current electrical device like an AC motor is turned on /off; or another crude example sometimes you have an inductive load sourced directly from AC mains controlled by a a manual bad switch and you turn the switch on/off. Sometimes one can even see some electric arc.
What type of noise is sent to the mains grid/wiring in these cases? I wonder how this kind of inductive switch effects other sensitive devices like TVs or radios or measurement systems for a short period of time.
Lets say there is a measurement system(transducer like an analog temperature sensor) and by using a coax cable it is send the measured voltage to an ADC.
And lets say that spiky inductive switching device and this transducer is powered from the same mains power plug or they are using the same line neutral.
How does the inductive spike route and effect the transducer or its coax line? Would that happen as a conductive or radiate way? How does the conductive way routes all the way to the transducer system?
The reason I'm asking is I'm wondering whether this type of noise through mains as conductive a common mode or differential noise. Would the spike/noise route through line or both line or neutral? How would it make it all the way to the coax through conduction?
Since it is impossible to track and see I cannot find an answer.
