Measurements performed using a TDR tester show that the time delay resulting from a power-line fault is 72.5 mS. The line-under- test has a velocity-factor of 0.67 and the echo pulse is non-inverted. Determine the distance to the power-line fault and discuss the significance of the measurement results.
Have I been 'sold a pup' with this question? I have no distance to measure so how can I get a location. As I understand it PL Fault/Velocity factor = X Which would then either be the distance or the power?
