Lines with Initial Conditions

3. Line with Initial Conditions

5. Example:

11. Uniform Distribution

13. t = 0.5 mS
t = 1.5 mS

14. t = 2.5 mS

15. Bounce Diagram Technique for
Uniform Distribution

18. Energy Storage in Transmission Lines
we, Electric stored energy density =
We, Electric stored energy =

19. wm, Magnetic stored energy density =

20. Check of Energy Balance
Initial stored energy

21. Energy dissipated in RL

22. System in steady state at t = 0–.
Another Example:
System in steady state at t = 0–.

23. t = 0–: steady state

24. t = 0+:

25. Solving, we obtain

26. Voltage
G = 0
G = 0
tV = 1

27. Current
G = 0, tC = 1
tCeff = 0.5
G = 0

28. t = 3 ms + : New steady state

29. t = 3 ms + :
