Is there a product that’s able to sense up to 300V with 0.001 increments? I think voltage transformers to 0-5v will not be able to reach 0.001 difference.
Something similar to Current and Voltage Sensor Board (https://www.digikey.com/catalog/en/partgroup/sen-16407-kr-sense-current-and-voltage-sensor-board-45a/107017) but for much higher voltage.
Hello Saisani,
Welcome to the community!
Fluke bench voltmeters can do this.
To give an example kindly see Fluke Mfg PN:
8808A 120V

Outside of that I don’t know much that can get down to that type of resolution and still be useful. You’re getting into tolerances that are usually kept for calibration laboratory equipment.
Hi,
I think you can find some on Amazon as well
