The current density inside a long solid cylindrical wire of radius a is in the direction of central axis and varies linearly with the distance from that axis r according to J=J0 r/a.
a. What is the range of the sensor voltage outputs initially and finally? b. What range of voltages would be expected to be measured 2 sec after the step change is applied?
define state variables, determine the required initial conditions, and use Matlab to solve for voltages Vc(t) and Vo(t). Plot the results, and verify that the numerical solution using state variables matches the hand calculation solution.
Evaluate the TL parameters. Include the effect of the earth as ideal. Do not incorporate the effect of the shield wires.
