How far can one use electrical wires before needing a transformer?

Like everything else, it depends.  The concern is that at the maximum current you will draw, there is sufficient voltage at the point of use.  Voltage drop depends on the amount of current, and the resistance of the circuit.  \n\nYou can determine the minimum voltage requirements for whatever you are driving.  Knowing the resistance per foot of various sizes of wire, you could determine the size wire needed.\n\nNow it becomes a matter of economics.  Is larger wire less expensive than a transformer--or two if you are going to maintain the original equipment operating voltage.

a ditisbution transformer is much larger . but they both do the same job .they either step up or step down current.

You need an energy transformer machine.  You put sound in, press the sound-to-electricity button and out comes electricity.  Make sure you have a storage cell attached or you'll get shocked.

Hi Ma...The answer may vary State to State/Privince etc..Even different Municipalities and Cities have their own rules...\n\nThe easiest way is to contact your local City planning dept...\nYou can't go wrong there....Generally the farther away from power poles, the better it is for safetys' sake...\n\nGood luck and please be careful... :)

Use a 12 volt lantern battery and some wires

Are you talking about the wire to supply the resistance heating wire or the resistance wire its self?\n\nThis is not something you should undertake in any way shape or form. It is something for a trained professional who has the experience and knowledge to install such a system safely.

If you have a 220v line going into your house, sure.  Otherwise.. no.  Most homes have 110/120 lines going into them.

No \nThere are no optimal frequencies for a transformer.

There are the two problems:\n1. Mechanical. The cable must be out of the way to prevent any mechanical damage or injury or even DEATH. \n2. Electrical. 1500 watts (~13.Amps at 120 Volts or 6.5A at 240 v could be better choice since a 6.5 A lesser wire gage can be used) will require at least a 10 gage (stranded) (or 14 gage for 6.5A) cable if you are running an inductive load (like motors). Resistive is more forgiving.\nThere is an easy way to estimate your circuit loading by placing a say 60w incandescent light bulb in series with you load at the end of your 500’ circuit and turning the load on. If the light dims and a lot you are in a little trouble. Do not test if your cable is coiled since as you realize you are adding inductance to the circuit.\n\nThis is an estimate. Consult electrical tables, licensed electrician  or equipment manufacturer for proper information.\n\nI hope it was useful.

First, what is the input voltage and the desired output voltage?  Is the output voltage fixed, or do you need a range of adjustment (taps)?  Do you need isolation between the input and the output?  If not, an autotransformer (single winding) might be acceptable.  What is the frequency, and is it single phase, three phase Y, or three phase delta?\n\nNext, what is the power rating?  Small transformers are usually rated in output current, whereas larger transformers are rated in KVA.  This is the maximum load;  a smaller load would not be a problem.\n\nFinally, what are the mechanical factors?  Does it need to be hermetic or can it be open frame?  Do you want terminals or wire leads?  What shape and size?  What is the mounting?\n\nIt's not really that hard.  Usually you can browse through a catalog and find the transformer you need in minutes.

Where are you going to plug in your DC heater?

Coil wires around it and run electricity through the wires.

Create an enclosure around it. There are plenty of acoustically dampening cloths. Use fireproof materials only. \nAlso make sure that the enclosure is vented.\n\nAs a precaution, leave an air gap of around three or four inches around all surfaces of the transformer's outside metal box. Lastly dont let the air inside ever get hot.

Razor wire, proper fencing and support for said razor wire, very heavy gloves (try grease gloves like used in fast food places) or just the heavyist gloves possible, a stapler to attach whatever, or wire or whatever your setting up. And be very god damn careful.

By reduces the target distance is one way to reduce power losses in transmission lines.\nuse capacitors and also a amplifiers as junction between sources and destination.\n\nstep transformer is more usefull.

1. Open transformer panel\n2. Lick fingers\n3. Grab wires from each end ensuring you are grounded well\n4. Feel the power of the almighty Zeus sticking a lightning bolt up your butt\n5. Close panel tightly\n6. Go somewhere other than Yahoo answers for Transformer Inspection Procedure
