Why a transformer designed for a 120V AC input will often burn out if connected to a 120V DC source?
All Transformers are designed to work on AC. They do not work on DC.
If you connect an inductor to DC, the current will increase until the capacity of the source or the conductance (1/resistance) capacity of the inductor and conductors is reached. Often, this condition will overheat and destroy the inductor, or destroy the source. A transformer is not an exception, as it is a form of inductor.
What else can I help you with?
Can a Dy11 vector group transformer be connected to a Yd1 vector group transformer source?
In series, yes. In parallel, nope! Putting a Yd1 transformer in series with a Dy11 transformer would result in the output of the Dy11 transformer being identical to the input of the Yd1 transformer with the exception of the voltage magnitude - this will change depending on the winding ratio's on both transformers. But, in regards to other properties of the voltage, the phases will in be in phase, with the voltage in-between the two transformers lagging by 30 degrees.
Why ghost power acting on a circuit?
Ghost power may be acting on a circuit if it has a capacitor or transformer connected. This will supply power long after the input has been disconnected.
What is the definition for Input high current and input low current?
Let me first correct the question "current" here should be "tension" current is the speed of the electrons moving through the conductor and tension is the EMF that make the electrons move you cannot input current. the current is the demand of the circuit, depending on the resistance and the EMF(Electro Motoric Force) in other words, the Volts that is applied or input to the circuit.Answer:Any transformer can be used as a up step(inverting) or down step(converting) transformer, for instance 220V - 6V will be a converting and the 220V side will be your primary or high tension input and if you turn it around the 6V side will be your primary or low tension input.
Why can't a DC electrical source connected to the input of a transformer induce the electrical flow from the transformer's output?
A transformer or generator works by changing magnetism into electricity when a magnet is turned on and off. You can move the magnets or you can create a break in the wire or use a switch or you can use alternating current. You need a way to turn the magnet on and off to change magnetic lines of force into electricity. So, to make your DC source work with your transformer, you must have a way to turn it on and off. Automobiles use a transistor to make the DC current from the Battery turn on and off so they can run it through a coil and have high voltage through the spark plugs.
If you have a 1000kva transformer than can you work on that transformer?
No. From what you're saying you're taking the input to the 2kV transformer in a microwave and replacing it with a 1MW input. The transformer will burn in milliseconds of power. <<>> The installation and maintenance of a 1000 KVA transformer can be worked on in a de energized state. To do so live could be extremely dangerous at any voltage.
The incoming voltage from the current source to the transformer is called what?
The incoming voltage from the source to the transformer is called primary voltage.
What happens if a 208VAC primary voltage is connected to a 240VAC stepdown transformer to 208VAC?
The transformer will act as a step down transformer in the ratio of 240 to 208. This will reduce the 208 input to 180.
What is the load side of a transformer?
The load side of a transformer feeds the device, such as a light or motor. It is the output of the transformer. The input, or line side, provides the voltage that is to be transformed, either up or down, to supply the load side.AnswerA transformer's primary winding is connected to the supply voltage, and the secondary winding is connected to the load.
What is the definition of audio-frequency transformer?
An audio frequency transformer is a transformer designed to operate in the range of frequencies audible to the average human. This range is generally accepted to be from 20 Hz to 20,000 Hz. The usual purpose of an audio transformer is to match impedances between circuit sections. For example: between a microphone and the input of an amplifier, (input transformer), or between the output of an amplifier and the loud speaker. (output transformer).
How many wires are input in a berry-type transformer?
1 wire is input in this type of transformer.
Can a Dy11 vector group transformer be connected to a Yd1 vector group transformer source?
In series, yes. In parallel, nope! Putting a Yd1 transformer in series with a Dy11 transformer would result in the output of the Dy11 transformer being identical to the input of the Yd1 transformer with the exception of the voltage magnitude - this will change depending on the winding ratio's on both transformers. But, in regards to other properties of the voltage, the phases will in be in phase, with the voltage in-between the two transformers lagging by 30 degrees.
What is the recommended voltage input for a 220 transformer?
The recommended voltage input for a 220 transformer is 220 volts.
What will happen if you pass AC current through a transformer?
If the transformer was designed for the specific frequency in use, it will step up or down voltage and current as it was designed to do. Transformers transform how power "looks" by increasing and decreasing voltage and current, while keeping power output equivalent to input (if you ignore the transformer losses).
You can use neutral to autotransformer?
Yes, but the transformer must have both the hot and neutral to work as designed. A auto-transformer is not a variable resistor that could reduce current/voltage by a change in the resistance which could be used in the hot and or neutral wire. An auto-transformer is designed to have the hot wire and neutral on each end of the winding with a variable tap in between. The resistance of the transformer and the inductance will effect the circuit to a limited way if placed in the neutral but this effect will not vary the voltage over the full range, the amount of voltage reduction will vary with the load's current draw, see ohms law. Neither a resistor or a auto-transformer connected in the neutral line only will increase the voltage above the level of the input like a correctly connected auto-transformer . Stanley
Why cant a 18V battery be used as the input of a transformer?
The transformer needs AC at its input. The battery provides DC.
What are the limitations of power supply?
Power limitation transformer circuit structure of power supply, including: an electromagnetic interference filter unit, a rectifying unit, a power factor correction section, a transformer having a primary input terminal and secondary input terminal, a pulse controlling unit connected with the secondary input terminal of the transformer, a primary power limitation circuit and at least one secondary power limitation circuit, an output current controlling unit and an output voltage controlling unit. The input terminal of the output current controlling unit is connected with the secondary output terminal of the transformer. The primary output terminal and secondary output terminal of the output current controlling unit are respectively serially connected with the primary and secondary power limitation circuits. The input terminal of the output voltage controlling unit is connected with the secondary output terminal of the transformer. The output terminal of the output voltage controlling unit is connected with the secondary power limitation circuit for controlling the magnitude of the voltage and current of the primary and secondary power limitation circuits so as to control the output power.
Why ghost power acting on a circuit?
Ghost power may be acting on a circuit if it has a capacitor or transformer connected. This will supply power long after the input has been disconnected.
