You have 480 volts coming into a stepdown transformer that is set for 440 volts incoming power would this cause your output voltage to be higher than 120 volts?
In short, probably. Transformers step power up or down by a multiplicative factor based on the number of turns in the two transformer coils. Therefore, if you put more voltage in you're going to get a proportional increase in the voltage out.
What else can I help you with?
How do you fix a b809d generator with under voltage problems?
AC card have over/under voltage adjustment for fault. If voltage drop to that range it will trip the fault. Also the unit have voltage adjustment in the bottom right. Voltage coming out of the cable vs voltage coming out Underwood can be different.
What do electric substations do?
Electric substations either step up voltage or step down voltage for electric power distribution. For example, power being generated at a power plant would be stepped up in voltage for transmission over the electric grid. On the other hand, power coming into a residential neighborhood from the electric grid would be stepped down in voltage for distribution to individual homes. This increasing or decreasing of voltage will be accomplished by using transformers in the substation. There will also be electric circuit breakers in the substation located on both the high and low voltage sides of the transformer. These circuit breakers are used to be able to isolate the transformer from the electric grid for maintenance purposes or in case of an electrical fault that could damage the transformer. Most substations will also contain a Control House that contains all of the control equipment for the substation as well as battery backups in case of loss of power. Type your answer here...
How do you drop voltage coming into a building just a few volts....It is just a bit too high and the power company says there is not much more they can do..............I am maxing out at 256 volts?
First thing to do is check your meter against a known voltage supply and make sure that the meter is zeroed out. On analog meters the needle can be adjust to the zero point on the scale. The chances are that you are very close to the supply transformer. The voltages are high in these locations to compensate for voltage drop further down the line. Some one on the end of the line may have complained about low voltage and this is why the voltage was boosted. If there are primary taps on the transformer they can be adjusted to lower the secondary voltage output. The power company usually does not believe the customer when the say the voltage is high or low. Check your 120 volts. Request that they send out one of their representatives to check your voltage. State that light bulbs are blowing frequently and not reaching their specified life. If your 240 voltage is high, the 120 volts will also be high. -------------------------------- If all that fails to correct the problem, you can install a 1 to 1 transformer with multiple taps prior to your main service panel. This will allow you to slightly reduce your voltage. This is not a job for an amateur. If properly sized and installed, the transformer will probably outlast any other piece of equipment. If improperly sized and installed, it can be a hazard and possibly deadly. -- Sparkfighter
What is function of auto transformer?
A transformer is a device that changes an electrical voltage or current from one level to another. (In radio frequency applications, it is used to couple the RF electronic circuits.)Transformers are used to:Convert high voltage alternating current (AC) to desired low voltage alternating current (AC). Such transformers are called step down transformers.Convert low voltage alternating current (AC) to desired high voltage alternating current (AC). Such transformers are called step up transformers.Electrically separate one part of the circuit (or any other electrical system) from the other part, termed as 'electrical isolation'. Such transformers are called isolation transformers.The transformation may involve the loss of some power as waste heat.(see related question)
How do you check 480 volts line coming from comed?
This high a voltage is an industrial voltage. If you are concerned about variations in the voltage call your utility supplier to get them to check it for you. They can connect a recording volt meter to the line an it gives a print out over a 24 hour period. If that is not an option call a qualified electrical contractor and ask him to take a reading for you. A voltage of 480 volts is not a voltage that the ordinary layman should be opening panels and getting into.
Is it possible to decrease voltage from 1562v to 30v using stepdown transformer?
Transformers step voltage up or down, so yes this is possible. This is a change of 1562/30 = 52, which is pretty high. It may be difficult to find a transformer made for this purpose. I've never heard of 1.56kV as a standard voltage. This seems a strange voltage. What is this coming from? A; Yes considering that a sub station will take transmission hi voltage to 16kv disribuition. and finally 240volts for us. the only consideration is breakdown and efficiency.
Type of transformers used in gas insulated substation?
Current transformer and voltage transformer . This transformers are actually measuring instruments which measures the quantity of current and voltage coming out of the substation.
What is that black box in a laptop power cord?
That is a transformer, it lowers the voltage coming from the plug to a lower voltage that the laptop can handle.
Why voltage of transformer go up beyond the set voltage when carrying out transformer test?
Transformers without regulators in them will output voltage depending on the voltage coming in. For instance if you have a 230v to 110v transformer then you will have a ratio of 23:11 this means for every 23 turns in the transformers primary side you will get 11 turns on the secondary, so if you have an input voltage of 247v then the output voltage will be around 118v, conversly if you have an inout voltage of 221v then the ouplut voltage will be around 106v.
What is the difference between a transformer and a rectifierwhich are found in a PC power supply?
The rectifier is what changes your AC into DC that the computer can use. Transformer raises or lowers the voltage. So you have 110 volts AC coming into your computers power supply. The Rectifier circuit in there changes the AC voltage to DC voltage but it is still to high for the computer use. The transformer lowers that voltage down to the various voltages that your computer needs
What is meant by high and low voltage sides of transformers?
Transformers are use to step up and step down the voltage of electricity. In a step up transformer, the voltage coming out is higher than the voltage going in so the output is the high side and the input the low side. In a step down transformer, the output is the low side.
Why isn't the current coming out of a transformer not a sine function?
The voltage of a transformer should be a sine wave but if the transformer is overloaded with excess voltage there could be nonlinear effects in the magnetic core that cause harmonics (i.e. departure from a sine wave) in the voltage. The current is determined by the load. If the load is resistive the current and voltage have the same waveform (by Ohm's law) but if the load is nonlinear, a diode rectifier for example, the current will depart from being a sine wave.
What is 132kva gridstation?
132 Kilo Volt Amps (kVA) is the amount of theoretical power being used by the transformer. The transformer takes high voltage from transmission lines and converts it to lower usable voltages. the power of 132 kVA comes from the product of current (I) and voltage (V) going into or coming out of the transformer. The gridstation as a whole takes in a few large power transmission lines, transforms their voltage, and distributes electricity to consumers.
How does a transformer affect the electricity coming into a home?
The transformer provides the electricity at the right voltage for the house. In all countries it makes sense for all the houses to be fed with the same voltage, which simplifies the market for electrical applicances. Most countries use a standard voltage in the range 100-125 v or 220-240 v. The electrical energy has to be transmitted over long distances at a higher voltage unless you want to live next to a generator, so the transformer changes the voltage from a higher voltage like 6600 v to the correct voltage for the house, e.g. 230 v.
What does a step-up transformer step up?
A step-up transformer steps up the voltage rather than stepping down the voltage like a normal ac wall adapter does. By stepping up the voltage it is not free electricity it allspice takes away from the available amps.e.g.Say you have 12V 1A AC going in to the primary coil of your step up transformer, this would result in a higher voltage and lesser amps like 24V 0.5A AC coming out of the secondary coil.AnswerA step-up transformer steps up voltage, but it DOES NOT 'step down' current! The secondary current is determined by the load, and the primary current is then determined by the value of secondary current.
Is transformer 3 coming out?
yes
