What are the advantages of High Voltage?
voltage is termed as electrical pressure. when high voltage is applied more is the movement of electrons. hence losses will be less. this is one of the major reason for which high voltage transmission is chosen.secondly due to high voltage the current will be less so as the conductor size
What happens when the voltage across a circuit increases?
It depends upon what the circuit is for and what components it contains. For example, increasing the voltage on a high-voltage transmission line will have very little effect, but a small increase in a micro-circuit could cause damage.AnswerIn general, an increase in voltage will result in an increase in current.
What is hvdc power transmission?
'HVDC' stands for high-voltage, direct current.
Which mode of transmission would result in less energy loss high current and low voltage or low current and high voltage Explain your reason?
low current high voltage power dissipation in power line = I2R the resistance of the power line is hard to reduce, especially when it is a long transmission line. but reducing the current through the line reduces losses as the square, a dramatic savings. reducing voltage would have no effect and would dramatically increase losses due to increase in current to try to deliver same power.
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 is high voltage good for?
High voltage is good for transmission of electricity since line losses are less with high voltage transmission.

What is the purpose of line trap?
A line trap is a set of physically-large inductors often seen hanging from transmission towers at the end of a high-voltage transmission line, where the line terminates at a substation. As transmission lines often carry data signals, which operate at frequencies very much higher than the 50-Hz (or 60-Hz) power frequency, the high inductive reactance* of the line traps act to prevent these signals from continuing beyond the end of that section of transmission line, while having an insignificant effect on the power-frequency load current.(*Inductive reactance is directly proportional to frequency)
Why signs reads Danger-High Voltage rather than Danger High Current?
Electricity is transferred with high voltage and low current to reduce transmission loss ( I2R , where R= resistance of wire). As high voltage is present in transmission lines, Danger-high voltage is written.
Why do power companies use high-voltage transmission lines?
High voltage lines are used for power transmission because the high voltage means that less current flows for a given amount of energy transmitted. The lower current flow means that the heating effect in the wires is smaller, so the wires stay cooler and lose less energy through heating.
Long distance transmission of electricity requires what?
High voltage.
How do you reduce transmission loss?
Transmission losses are less in HV or EHV transmission lines. Higher the voltage lower the losses. High voltage DC transmission is another way to have less transmission losses.
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.

How a transformer is so important?
Transformers transform low vvoltages to hivh and vice versa. This is important in transmitting electrical power form the high voltage power plant to the low voltage home voltage. Using high voltage transmission reduces transmission power losses, I2R.
