this project have completely describe the instrumentation of sensor and its connection, check this out it will be really help full. connect detail of arduino and ESP32 connections.
It means actual winding power handling capacity is only 1015 KVA but this autotransformer can handle 5000 KVA means auto transformer can handle 5 times more power and 5 times smaller than a conventional 2 winding transformer
An electromagnet can be used for moving scrap steel from one place to another. In a scrapyard, a crane has a large iron disc that is not a permanent magnet. The crane operator lowers the electromagnet into a pile of scrap steel and then switches on the electricity.

this will help you in doing replacement of the joystick using reed switch. this project discussion will help you understand counter going to the digital pot.
we can use MVA Method, 40MVA in series with 25 MVA (1MVA/.04)
and 40 X 25 / (40+25) = 15.38 MVA
we find out that Fault is on the 480v bus
15.38MVA/(sqrt(3) * 480e-6MV) = 18,500A
To create a wirewound resistor, one piece of wire would have to serve as the path for the electrical current to flow from one end of the resistor to the other. To create a resistor with a small resistance (or Ohm) value, use a thicker, shorter wire as the path between the two electrical leads.
