Background
I am working on a power grid project where I need to be able to switch in another source when the first source cannot supply the power needed by the load.
Problem
How do I calculate the load on the other side of the transmission lines? Taking measurements after the transmission line is not an option. The source is 120V AC
My attempt at a solution
Measure current by measuring voltage across a "sensing" resistor before the transmission lines. Since voltage is known (120) and current is known via the sensing resistor, the load can be calculated.
edit: This may be related to the area of fault detection
