What is High voltage: Definition and 162 Discussions
High voltage electricity refers to electrical potential large enough to cause injury or damage. In certain industries, high voltage refers to voltage above a certain threshold. Equipment and conductors that carry high voltage warrant special safety requirements and procedures.
High voltage is used in electrical power distribution, in cathode ray tubes, to generate X-rays and particle beams, to produce electrical arcs, for ignition, in photomultiplier tubes, and in high-power amplifier vacuum tubes, as well as other industrial, military and scientific applications.
You hear from me first. I claim, “We can apply very high voltage on deuterium to achieve fusion power generation.” Using a device like a van De Graaff or Tesla Coils machine, we can generate very high voltage with minimum power input on a deuterium gas mixture which surrounds a pullet. The...
It is so surprising that athe Wimshurst machine can generate up tp 1,000,000 voltage with the size of 50 cm!
As I know, in order to generate such a high voltage on its 2 terminals, there must be a very large quantity of charges being "collected and stored" in the Leyden Jars.
Am I right...

Let me explain what happened.
There is a great scenic overlook on top of the Appalachian Trail near my house. The overlook is mainly there because a power line travels up the mountain, and that section of the hill is clear cut to keep the trees out of the lines. The view is...
Hi all,
I'd like to know what these rings at high voltage connectors are good for:

Hi all,
Can anybody help me on HVs, high voltages up to 60Kv? Actually I've got this HV supply , then i came across with an old ammeter in my garage which i thought could help in showing me the exact voltage my supply is transferring but i have a poblem in matching the resistances. actually i...
Hi Group,
I'm interested in how and why ozone is produced by high voltage discharges. I was hoping that if I give my impression of how the process works, people could correct any mistakes I've made. Here's how I think the process works:
1) Let's pretend a large high voltage arc is...
Why over long distance power transmissions do we use a high voltage and not a high current?
I'm curious about this, I have a test tomorrow and totally forgot to ask the teacher for the answer and got a test tomorrow. :bugeye:
I'd appreciate if someone could help me out here!
Thanks.
I have recently read about people who have successfully taken electricity from high voltage lines and used it to power their homes. Is this possible? What voltage, current and power can you get from it? What extra equipment is needed to make this work successfully?
Please help me wif these problems! I have no idea.
A person with a body resistance between his hands of 10 kohms accidently grasps the terminals of a 20 kV power supply.
(a) Draw a circuit diagram including all the data.
(b) If the internal resistance of the power supply is 2000 ohmns, what...
Hello,
I am working on an investigation and was wondering if you could help me with some information. There was an occurrence on a ship involving high voltage and am looking at the necessity of recommending training for the crew members. The crew was trained in 440V systems, but they were...
Here is the question:
A high Voltage line with a resistance of .18 ohms/km carries a current of 1525A. The line is at a potential of 1500 kV at the powerstation and caries to current to a city located 192 km away. What is the power loss due to resistance in the line. Answer in units of MW...
What is commonly the voltage in the high voltage lines used to transport electric energy over large distances? What is their resistance and inductance? What is the magnitude of the current flowing there?
