When do special precautions need to be taken when working near overhead electric power lines?
Usually you would want to stay at least 10 feet away from power lines. Any conductive material you are working with also has to be at least 10 feet away (metal extension ladder).
How do you choose no of insulator in High Voltage transmission Line?
Each insulator is rated according to its ability to insulate. For example, if one insulator is good for x volts, then four insulators will be required for a line conductor operating at 4x volts with respect to earth (ground). However, additional insulators might also be inserted to compensate for local conditions -e.g. salt deposit (near the sea), industrial pollution (near factories), etc.
Four causes of faults on transmission lines?
Some cases I've seen: -Nature: -lightning strikes near line -fires (I've seen farmers burn weeds out from under a line - the fire ionizes the air, and with the added particulates in the air create a path to ground) -snow storms/icing on lines (can cause lines to sag) -high winds (can cause lines to blow out, possibly making contact with trees, or can cause enough stress to break poles). Winds can also blow stuff into the lines -tornados -Animals: -Two bears climbing a pole -Two owls fighting near a line -Eagle/other large birds swooping down between conductors -Eagle/other large bird pooping on conductors -People: -farmers touching power lines with harvesting equipment -crop dusters attempting to fly under lines -people crashing cars into poles
What safety precautions should be taken during maintanence of a 11000 volt line?
11 kV power lines are extremely dangerous and there are many safety requirements. The main principle is that this work must be done by trained and qualified personnel. Some of the protocols include always wearing a hardhat and protective boots, and never going near such power alone.
How safe is a city near a nuclear power plant?
Usually very, often safer than one near a coal plant.
Is it safe to fly a kite near resendential street power lines?
No.
Why do overhead electric power lines make noise?
The 'buzzing' noise associated with power lines is due to the chemical breakdown of the air due to intense electric fields. This is at its greatest in the vicinity of sharp-edged conducting components which occur near the insulators which support the power lines This effect also accounts for the hazy blue discharge often seen at night. The effect is at its greatest during damp conditions.On the other hand, the 'humming' heard from transformers is due to the 50- or 60-Hz electromagnetic forces on the device's laminated core.
Is living near power lines dangerous?
Very dangerous. You should avoid these lines at all cost and immediately call you power company.
Is it safe to raise kids under high voltage power lines?
There is no scientific evidence to suggest that living near power lines causes any kind of health problems.
Why do you think compass might not work near storm power lines?
Compasses do not work well in the presence of of electromagnetic fields.
What can you do to help yourself now if waterlines and power lines and roads are damaged during an earthquake?
stay less out of harms way mostly if you are anywhere near the power lines or road or waterlines its best to find a safe place like a building closer to where you are try to be patient when the first earthquake happens do not panic. Panicng can make it hard for you to focus and get to a safety.
Are you opposed to nuclear power?
No, nuclear power is a decent source of energy, depending upon the reactor design and siting. Locating reactors over fault lines or near ocean shore lines seems unwise.
What are the colored balls on power lines usually near water about the size of a basketball?
The colored balls on power lines are a warning indicator for low-flying aircrafts. The FAA mandates their existence as some sources say power line strikes are the leading cause of helicopter crashes.
Pokemon SoulSilver where to find electebuzz?
you will find sum electabuzz near the power plant. i assume you can get to the power plant. its kinda rare, and may take awhile to find.
Where do you put fluid on a 1995 Mazda Bongo?
At the power steering resivoir. Find the pump and you will find the resivoir near it or on it.
When did the United States stop using DC power in your homes?
We never did, that battle was lost before electrical transmissions lines where anywhere near common.
When do special precautions need to be taken when working near overhead electric power lines?
Usually you would want to stay at least 10 feet away from power lines. Any conductive material you are working with also has to be at least 10 feet away (metal extension ladder).
