How far can power line be from house to pole without transformer?

It depends on the total load spread along the line and the voltage drop at full load at the end of the line. Generally up to 3 % voltage drop is considered ok. Anything beyond you need another transformer center.

∙ 7y agoThere is no set distance. You just have to keep increasing the size of the feeder conductors the further the distance becomes. It is all to do with voltage drop. The further from the voltage source the voltage drops off due to the internal resistance of the feeder conductor.
There are many voltage drop calculators on the internet. All you have to do in insert the voltage you are using, the amperage that you want at the end of the feeder run and the distance that you want to run the feeder line. It will calculate the size of the conductor needed to fulfill your parameters that you added to calculate your feeder size. These calculators usually calculate to a voltage drop of 3% which is fine for a home distribution system.

What is the purpose of a transformer?
It steps down voltage by moving the iron core spacing. Mostly using on high current welding transformer. Easy to achieve changing output voltageand does not need to use high power selector to switch voltage
If you plug a generator into your house what will happen?
You have it the wrong way around, you plug the load into your generator. Never plug a generator into a house unless you have the proper disconnect installed. To do so will put you and your house in danger. Plus you are a danger to anyone working on the main line supplying power to your house. Things that could happen. 1 You could feed power to the main line which can kill or injure anyone working on the main line. 2 Without the proper control switch. You could be subject to large fines. 3 If the power company finds out. They could pull your meter. Taking your house off the grid. 4 You will be liable for any damage you cause. Also your insurance could be canceled. 5 If power comes back and back feeds your genset. It will turn into a smoking pile of junk. 6 If you need a generator at your house. Have it installed the proper way by a company that does installs.
Which part of the electrical line is responsible in reducing the voltage to 220 volts in residential places?
Its not a part of the line but a different component in the circuit called the transformer. The step down transformer is responsible for reducing the voltage that is brought to it from the company main line. It follows the law of electromagnetic induction.
What is line side amps for 1000kva transformer?
It depends on the voltage on line side. KVA is simply thousand volt-amps, so you need to know voltage in order to calculate amperes.Another AnswerThe rated primary current is the rated apparent power of the transformer, divided by the rated primary current. However, the actual primary current is determined by the actualsecondary load current in proportion to the reciprocal of the turns ratio.
Are you liable if your tree causes a power surge inside your house after rubbing a power line in the yard?
Liable? No. But you may want to get your tree trimmed so that it does not happen again.
Is there a basic difference between a three phase power transformer and a three phase distribution transformer?
The basic difference is the secondary voltages. On a distribution transformer the secondary voltage is very high. This is to overcome line loss for transmission of electricity over long distances. A three phase power transformer is used at the consumers three phase services end to manipulate voltages that consumers need to operate their equipment. The transformer that feeds your house is considered to be a single phase power transformer.
What is the result when 3 kva power requirement is being supplied by 250 kva transformer?
The result is that the transformer runs cool and contented. The '250 KVA' rating on the transformer is its maximum ability to transfer power from its input to its output without overheating, NOT an amount of power always running through it. If the 3 KVA load happens to be the only thing connected to the transformer at the time, then only 3 KVA flows into the transformer from the primary line, and only 3 KVA leaves the transformer secondary.
How to stop hum where power line is tied to house at second story Distribution box is in basement?
Probably the only way is to eliminate the overhead powerline and bury the cable from transformer to the house. The wires will always telegraph sounds from the powerline and/or power poles.
What do you call A device that increases or decreases voltage in a power line is a?
A transformer can perform this function.
What is unit transformer?
UniT transformer are step up transformer which is connected to generating house & step up voltage from 11/15kV votlage to 220/400kV voltage level as requirement or line design parameter. It is just like transformer but connected to unit of the generating house that's why we called it unit transformers.
What do you mean by line in and line out in power system?
A1: Usually this is in reference to a transformer that either steps up or steps down the Line Voltage. For example if your house line voltage was 120 VAC and this voltage was attached to the input (Primary) or a transformer, the output side of the transformer might step up the voltage to 240 VAC. This would be called line out voltage on the secondary of the transformer. A2: In case the question was related to audio signalling and amplification, Line In and Line Out are low level inputs and outputs of audio signals, often using RCA phono jacks, such as what is connected between a tape deck or CD player and your mixer or amplifier with coaxial cables.
If a landlord runs his or her business on the same property as the house can he have the power to the business running through the line that you pay for?
Not without your permission.
How does engery get from a power plant to a house?
through a power line : )
When step down transformer is activated what happens?
Step down transformer reduces high voltage of main power line and distribute it to desired level of voltage usable by residence or devices.
How do you replace a European plug with a North American plug?
I would caution you that it might be dangerous to do that. The voltages of the electricity supplied to houses in some European countries differ from the one on this continent. For anything short-term, they sell converters that can protect your equipment when plugging into a non-standard outlet, which would be much safer. However, to answer your question, in a European house you would need the final line transformer providing 230V from the power company to have a center tapped neutral, which they do not currently have, and so you would have to have a custom transformer... who knows what that would take in terms of safety regulations or permits. (In the US 240V is the main voltage coming into the house, and they use a center tapped transformer secondary tied to house neutral on the house side. The voltages available inside the US house are 120V from each line to neutral and 240V from line to line.)
How do you calculate power for a delta connected three phase autotransformer?
The maximum power output of the transformer is measured in VA or KVA, (volt-amps) or thousand (volt-amps). That will will marked or stamped on the transformer. If you want to measure the amount of power being used by the Xformer, measure the Line side current in amps with an amprobe and multiply by the line voltage to it. The result in watts is the power consumption.
What is the power line voltage between phase and earthing?
It is the same as phase to neutral. As the neutral is earthed at the electricity suppliers transformer.
