Hi
I am working on a small project, where I need to be able to detect flowing current on the existing pump power control unit.
I would like to be able to detect when a pump has tripped(by the protection circuit) and pass this information remotely. At the moment, when every issue arise the LAMP is switched on and if I am correct I can simply measure the current flow
I would like to either use the standard clip-on of the current transformer sensor or the hall effect clip-on of the sensor.
As I am detecting the current going to a lamp @ 24VAC, would there be a minimum current requirement for sensors to accurately detect current flow? Or can it detect a few mA?
In addition to this, the pump is powered using 3 phases, can on clip-sensor be sufficient for that or would we need to use the sensor for each phase?
I would like to use a Non-Invasive Sensor as I do not want to play around in-depth with high power.
Is there any good manufacturer that I should be looking at? I found the following
https://www.poweruc.pl/collections/split-core-current-transformers2
Do these types of sensors require any calibration?
Are all the outputs generally analogue or can you get versions with maybe pulse or digital signal?
Thanks
This is the circuit that I need to add the sensors to.
I need to measure High-Level Lamp, Overload Tripped Load lamp connection.
