What are the disadvantages of transmitting electric power at high voltage levels?

The main disadvantage is that high voltage causes surrounding air ionization and may cause negative health effects for people close by. However, electric losses will be less when electricity is transmitted at high voltage. The higher the voltage the less the electric losses.

∙ 15y agoit's more dangerous, morlikley to arc across to objects, but there is alot amps drop when the voltage is reduced, that's why the electric companys do it

Can a a electric substation in a city use transformers to increase the power output?
No! A transformer changes voltage levels, not power levels. In fact, the output power of a transformer is actually a little lower than its input power, due to the efficiency of a transformer.
What are the generation voltage levels in VTPS?
The generation voltage of vtps is a variation of many different principles.
Which conditions refers to a reduced voltage levels of AC power that lasts for a period of time?
Reduced voltage levels of AC power that lasts for a period of time is known as a brownout.
What are the advantages and disadvantages of the rise and fall method in surveying?
1, describe the methode of reducing the levels and thier relative advantages and disadvantages 2, writetypes of levelling instruments and methodes of leveling
What is the formula to convert voltage levels to decibels?
Here you find the formula to convert voltage levels to decibels. Scroll down to related links and look at "How to calculate dB?"
What are the advantages of transmitting electric power at high voltage levels?
For a given amount of power, the higher the voltage the lower the current. This is necessary to minimise the voltage drop along the transmission line, and to reduce energy losses which are proportional to current squared. The advantage of transmiting electrical power at high(er) voltages is that you can use smaller conductors, since the current flow would be less for the same amount of watts. Watts = Volts times Amperes
What is the voltage range at which power is transmitted?
CSA C235-83-CAN3 Preferred Voltage Levels for AC Systems, 0 to 50,000 V Electric Power Transmission and Distribution
How many voltage levels does a digital systems need?
number of finite voltage levels
Why is electical power transmitted with high voltage?
For a given load, the higher the supply voltage, the lower the resulting load current. So, by transmitting electrical energy at very high voltages, the load current will be low enough to: (1) reduce line voltage drops to managable levels (2) allow the use of cables of practical sizes (3) minimise line losses
How are signals converted from voltage levels to their corresponding decibel equivalents and from decibel levels to their corresponding voltage or current levels?
Scroll down to related links and look at "Conversion Voltage V to voltage level Lu and LV - Decibel (dB) level conversion to volt ".
Can a a electric substation in a city use transformers to increase the power output?
No! A transformer changes voltage levels, not power levels. In fact, the output power of a transformer is actually a little lower than its input power, due to the efficiency of a transformer.
How is the voltage for homes shipped to a home?
Voltage isn't "shipped", really. Generator terminal voltage is typically in the range of 10-30kV; they are connected to the bulk electric system by step up transformers that convert this 10-30kV into voltage in excess of 100kV for power transmission. Near your home, this voltage is again stepped down to sub transmission voltage levels, then distribution voltage levels. The small power lines near your home are probably distribution level power lines (often 2 - 20kV); these will have a center tapped step down transformer to connect your home, at 120volts, to the grid.
What are the disadvantages of step down transformers?
There are no disadvantages to either step-up, or to step-down, transformers. They do exactly what they are intended to do: change voltage levels while maintaining approximately the same power level on both primary and secondary sides.
What is 232 in RS232 and MAX232?
The difference between max232 and rs232 is the voltage levels of the rs232 are high. In order to reduce those voltage means to convert those voltage levels to TTL logic levels we use max232 integrated chip which is a dual driver/ receiver.
What are the generation voltage levels in VTPS?
The generation voltage of vtps is a variation of many different principles.
How do you convert signals from voltage levels to their corresponding decibel equivalents and from decibel levels to their corresponding voltage or current levels?
convert signal gains or losses to comparative decible reading.
What in a substations reduces the transmission voltage levels?
Transformers.
