because you will get shocked
High voltages are not used in residential settings primarily because of electro-magnetic interference. Although it would be much more efficient you would never be able to watch tv,listen to a radio...etc.
AnswerHigh voltages are only necessary for the transmission and distribution of electricity; the reasons for this simply don't apply at the point of use. The hazards involved with high voltage make it completely unsuitable for use in the home.

High AC voltages are usually measured with?
They are usually measured using potential transformers that lower the voltages so that normal metering equipment can be used. Potential transformers PT's are almost no different that regular transformers except they are designed to be extremely accurate since they are used for metering purposes.
What is an alternating current transmitted at high voltages but usually at low voltages?
I assume you mean "Why" rather than "What". Simply stated, there are fewer transmission losses using high voltage, so the large power lines run at high voltage, but for home use, high voltage would be dangerous and would require considerably more insulation, so it is stepped down to about 115V RMS (root mean square average) for home use. Fewer people get killed and fewer houses burn down that way.
What is service voltage?
The voltage at the service, such as a customer (your home, for example). This may be contrasted with the transmission, subtransmission, and distribution voltages used to get power from the generator to the customer.
Why is alternating current low voltage?
Alternating current is not necessairly low voltage, on the controrary AC is more oftenly used for when high voltage is needed. Most power distribution systems (extremely high voltages) use AC because AC is easier to transform to high voltages (using the aptly named transformer). High voltage is needed for power distribution to decreases losses due to transmission.
What is the high pod test?
A high pot test is a test of a wiring system for high potential (voltages). It's also called a megger test. This test verifies the integrity of a wire's insulation, and ensures that high voltages cannot escape through cracks in the insulation smaller than the human eye can see.
What is instrument potential transformer?
it is used to measure very high voltages which can not be measured with volt meter.
Why are power lines run at high voltages?
Power lines run at high voltages to overcome line loss.
Why are transformers used for transmission of electricity into your home?
The voltage provided by power company are higher what your home uses so transformers step down the voltage for your house. Higher voltages in your home would cause a potential safety hazard. The higher voltages on transmission lines are used to cope with voltage drops over long distances.
Can high voltage electricity be at home?
NO.No device or equipment at home are high voltage type. Hence it is not necessary to have HV at home.AnswerDevices that require high voltages, such as CRT television, electrostatic loudspeakers, etc., have transformers that increase the supply voltage to that voltage.
Why are a range of voltages used?
Several reasons for different voltages. At the heart of it is that to deliver the same power, voltage and current are inversely related. The other aspect is safety. So for the grid, high voltages are used to maximize power transmission within the current limits of the cables. In industrial environments, equipment may require a lot of power - that requires high voltages as well Domestic requirements are not so power-hungry so 120 or 240 volts are adequate, and are also safer (well... less dangerous) than higher voltages.
Why a fuse of high voltage is used for electrical appliances of less voltages in comparison to fuse?
for those appliances do not break immediately...........
What are grounding mats used for?
Grounding mats are used when working on electronic components to drain off static electricity. Static electricity develops high voltages (the spark that jumps from your hand to a doorknob in winter is static electricity) and these voltages can damage sensitive electronics.
What two voltages do you have in your home?
I'm not sure they're "voltages" but if you're talking about the circuits, then the two types are series and paralllel.
Why air circuit breaker is not using for high voltage?
Air circuit brakers is not used in high voltages because, when comparing the high voltage the dielectric strength of air is low. By nandhagopal theni.ph 7200801043.
High AC voltages are usually measured with?
They are usually measured using potential transformers that lower the voltages so that normal metering equipment can be used. Potential transformers PT's are almost no different that regular transformers except they are designed to be extremely accurate since they are used for metering purposes.
What we check kiln during operations?
Kilns operate at high temperatures and make use of high voltages and if improperly installed, maintained, or used it can cause serious personal or property damages.
What is high voltage in marine system?
In the marine system, what is considered high voltages are 3.3 kV, 6.6 kV, and 11 kV. The low voltages, on the other hand, are below 1 kV.
