because in laboratory almost we are using only three phase equipents,so we require more pewer in laboratory, thats why we are generating high voltage in laboratory.

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 are the standard voltages for transmission?
The standard voltage for transmission is about 115 to 1,200 kV (long-distance transmission). The extreme high voltages are measured more than 2,000 kV and it is exists between conductor and ground.Answer for UKThe standard transmission voltages in the UK are 400 kV and 275 kV. Primary distribution voltages are 132 kV and 33 kV, and secondary distribution voltages are 11 kV and 400 V. These are all line voltages -i.e. voltages measured between line conductors.
When electricity travels long distances it is better to have it at higher voltages?
when transmission we usually use high voltages becoz at higher voltages current is less(p=vi,voltage is inversly proportional to current at constant power) so that we can minimize copper losses i2R losses.
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.
Why are high voltages not used in the home?
because you will get shockedHigh 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.
Electric current from a generating plant is?
Electric current from a generating plant is a alternating current transmitted at high voltages, but usually used at low voltages.
What is the need for generating high voltages in laboratories?
we generate high voltage (DC,AC or Impuse) purposely for insulation testing of various components in power systems. Physics labs need high voltage to accelerate subatomic particles.
Why are power lines run at high voltages?
Power lines run at high voltages to overcome line loss.
What do you do if laboratory glassware and microscopes are stored on a high open shelf in an earthquake?
I need this for my project and I cant get any info

Where is a good laboratory to test out High voltage experiments?
A good laboratory to test out high voltage experiment should be a government owned laboratory, or one that is government approved.
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.
What are some cautions to electrical energy?
It's dangerous at high voltages.
