An ignition coil is an autotransformer, the primary and secondary windings are indeed tied together
this is so IN SOME INSTANCES ONLY.
otherwise, you have just invalidated many many repairs that were successfully and properly diagnosed with ohmeters.
I wasn't trying to demonstrate stellar expertise in my post.....only wanted to answer the question with some rudiments. YOU should look into the automotive world to discover which coils are inductive discharge and which are capacitive discharge.....
If the power company has made the land unusable by misplacing the transmission lines then the power company is responsible for reimbursing the owners for the use of their property. Also the power company would be responsible for any persons injured by this action.
Depends. If National Grid put that thing up a goodly number of years ago (it's about ten in my state) and occupied it without protest from the underlying owner, then they have effectively a sort of "squatters" easement on the property. It's sort of like letting everyone use the back thirty feet of your property to get in and out of their place, even though they have other means to do so. Eventually, they acquire a common law "right" in your land, if they do so without express permission.
I spent twenty five years as a title examiner, and we expressly excluded such things from coverage, since they could not be determined from the legal record on file with the county.
I think there's a difference between "safe approach distance" and "no annoying effects on electrical appliances" distance.
Boo, hiss.
Common sense is an oxymoron. What passes for good sense is far from common anymore.
Then again, looking at the pic of that guy, you can see where the pancake makeup is covering up the tumors...[/sarc]
Regardless, it seems like a owning this home has been a NEGATIVE experience. It does seem unfair that the utility company is CHARGING him although that doesn't give him the right to CIRCUIT-Vent the law (ohm's law that is...)
How does your electric toothbrush charge even though there's no metal contact between the toothbrush and the charger stand? 61 & 63 answered well.
I'm sorry but I could not understand what you were explaining. Think in terms of energy conversion. You put energy in a box, like squeezing a spring. When the spring is released the energy stored is released, with the florescent bulb the energy is released in the form of visible light.
This was in Massachusetts.
They ran all of the beneficial "senses" out of state immediately after July 18, 1969.
And they never got them back.
You see a problem, I see opportunity. Honestly, the magnetic field off these lines is just wasted power, and I think it's good to collect it. The power companies should just lease transformers to those people who are near such lines. Unless I'm misunderstanding something, it should also help the load on the grid.
No not really. His construction may have started before the power line transmission. If he had the permits BEFORE the towers were actually put up he has a good case as power companies are known to LIE about their tower placements. I've had it done to me. For example he as well as the county Building Inspector could have been told it was a vertical single pole tower and could have changed to a dual tower arrangement throwing off all Right of Way calculations.
I will say this much when TVA put a 180,000 volt transmission on my property and a new sub-station nearby it caused me a lot of grief. The first thing was my utility upped my service voltage from 115/230 to 128/256 volts and I started having appliances burn up as well as my deep well pump several times. They were running the voltages hot to help pay for the cost of the new substation. IOW a back door rate increase. I made some threats of litigation against the local utility and they placed a 115/230 transformer on my home resolving that issue.
Depending on how good the ground grid is in the area is another determining factor. I've had the bleed off from lightning hits on the tower blow through my lightning arrestors on my fence as well and come in on my house. My home is very well grounded. But IIRC the minimum distance allowed for a dwelling to a Transmission Line is roughly 50 feet.
I'd like to hear the mans side of it before labeling him an idiot as power companies can be bullies when it comes to power lines and out and out liars. He made have been told he met the initial requirements when he began construction. If so the utility company owes him a house and payoff on the loan.
I should have added my home was built twenty years ago in a rual community. It is not a McMansion, but a simple single story wood frame on a concrete slab. It is not fancy, but it is paid for.
I don't have to negotiate with the radio station to make use of its electromagnetic transmissions onto my property.
If your Va messes with my KVA generated, it's billable, and no, it doesn't help the system. I think your misunderstanding.
Then time to help here. Does doing this put any amount of strain on the system, create any amount of loss on the system? Or does it just take advantage of what's already been lost? I understand your position if it creates even the tiniest amount of loss.
The external field accelerates the ions. Energy is transferred from the field to the ion, transforming electrical potential to kinetic energy. (The flow of ions cancels the electric field, like a capacitor charging up, so the electrostatic field energy decreases) The ions collide with other molecules, ionizing them and thereby transforming some of their kinetic energy into electrical energy, in the form of the ionization potential. (It takes energy to knock the electrons away from the molecules.) The external electric field thereby greatly increases the number of ionized molecules. Everytime an ion recombines with an electron, voila, electrostatic potential energy is transformed into electromagnetic radiation. Let there be light!
E-field --> {accelerates ions}--> kinetic energy --> {collision/ionization} --> electrostatic energy --> recombination --> electromagnetic radiation (light!)
If his house is within 27 feet of a 345 KV line, then he built it on the power company's right of way.
The principal means of coupling is through the electric field. Figure a peak potential of maybe 300 KV, and a distance to ground of 30 Meters, and you have around 10 KV/M field strength right there.
The coupling due to magnetic fields is comparatively minor, and would fluctuate as the current being carried by the powerline fluctuated.
As far as biological effects, effects from alternating magnetic fields are more difficult to demonstrate than those from electric fields.
(Note that I am not talking here about electromagnetic radiation; only the separate effects of electric or magnetic fields need be considered in this case.)
I once lived under some 100+KV lines--about 70 feet distant--and the main effect was to make hum in my condenser microphones.
