What are two major ways to reduce the phase‐to‐neutral
capacitance of overhead transmission lines?
How does this compare to methods used to reduce line
inductance?
How does a capacitance affect Long Transmission lines? If the
receiving end of the long transmission is open circuited, is there
a current flow at the sending end?
A two 3- phase transmission lines A & B have the following
data: VS = VR = 33 KV/ph , ZA = 2 + j 5 Ω/ph & ZB = 1 + j 6
Ω/ph. Each one delivering 10 MVA at unity p.f. Find:
(a)Voltage regulation (b) efficiency and (c) load angle of each
T.L.
Q \ What are transmission lines and what are the
effects and causes of transmission lines, then mention the
difference between the spread of electromagnetic waves in
transmission lines and spread in free space?
In a localized capacitance method for a Long transmission line
what could be consider a drawback from it? Also when a long
transmission line is open circuited on its receiving end, would
there be any current at the sending end?

1. What was the equivalent capacitance for two capacitors in
series? What was the equivalent capacitance for two capacitors in
parallel?
2. How is the charge on a capacitor found?
3. What held more total charge, capacitors in series or in
parallel?
4. How does current flow in a circuit with a capacitor if the
two plates in a capacitor are not connected by a conductor?
5. What do each of the four lines on a resistor mean? (Give four...
