The balls on overhead conductors are, belive it or not to make them visable to birds, helecoptors and planes etc, so they wont fly in to them. They have no electrical purpose what so ever, Sorry to sat its that simple!! Colin

What are the applications of high voltage?
some of the applications which i think are:high voltage power transmissioninsulation testingmeasurement of insulation resistancebreakdown voltage measurementsmeasurement of electric stress on different materialstesting of power transmission equipmentslightning simulationstudy of high voltages transients/surges on transmission lines
What does inductive load effect on High Voltage transmission line?
the inductive load which is generally use in high voltage transmission line known as transformer. the transformer transform the high voltage to low voltage.
What is an example of a step-up transformer?
Power stations use step-up transformers to transmit power at a high voltage instead of a high current. This reduces the power lost in the transmission lines.
Why neutral is not required for vacuum circuit breaker?
Air-blast circuit breakers are used to disconnect high-voltage transmission or distribution circuits in the event of a fault. One circuit breaker is required for each of the three line conductors; there is not normally a neutral conductor in high-voltage three-phase transmission/distribution lines.
How are step-up and step-down transformers used in the transmission of electric current from the electric company to homes?
(This is what my teacher said, I wrote this down in my notes) The answer is, Step-up transformers are used to increase the voltage of an electric current before it is sent out over transmission lines from the electric company. Step-down transformers are used to reduce the voltage of current from high-voltage transmission lines before it enters homes and businesses. Some devices, such as televisions, contain step-up transformers that increase the voltage once again.
What is distance protection in high voltage transmission lines?

Why transmission is done on 11kv and 33kv?
High voltage reduces the amount of energy wasted in transmission lines.
Why are there sometimes balls on high voltage electrical wires?
The balls on some power lines are required so that airplane pilots will be able to avoid flying into the lines.
How can measure the voltage only seeing the insulators in a high voltage transmission lines?
i think 11kv per insulator
Are high voltage transmission lines 60Hz like the wiring in a house?
Yes, the frequency stays the same. Only the voltage and current change as the voltage is stepped down.
Why overhead transmission lines would be more economical than underground transmission lines in high voltage transmission?
Overhead wires do not require insulation, and it is easier to plant poles than dig miles of trenches.
Why is high voltage a plus?
its because of transformers . they work with pulse

Why does corona effect is more in village than in city under transmission lines?
for sake of safety and protection the high voltage transmission lines are erected in less populated areas ie. villages , these lines have operating voltages about 220kv , 440kv , 132 kv( high tension lines) . while in cities the voltage is distributed at low voltages ( about 11kv(industry) , 440v residential ) because of safety issue . since corona loss highly depends on the operating voltage of lines thats why it is mostly seen in villages.
How are electrical insulators made?
The insulators used on high tension transmission lines and on distribution lines are made of either glass or ceramic shaped in a mold. On high tension lines several are typically stacked to create a compound insulator that can avoid arcing at the voltage on the lines.
Why is high voltage from 11kv onwards?
To be precise this kind of hi voltage is called distribution by power company. 11kv 16 kv that type of voltage. however transmission can be in the range of 5ookv. And you can see at tower from interstates lines
