Hi, I’m not able to figure out what does permanent magnets contribute in the whole chain of smart electricity meters. In the smart meters, there is board etched with circuits which are done at the stage of preparing the PCB.
I watched this video: How It’s Made: Smart Electric Meters – YouTube . I think this more or less captures the manufacturing of Smart meters. I can visualize where the magnets would have been used in old meters but can someone point where it is being used in smart meteres?
