We need to build some basic principles of tension before they expand into transformers. What is current, voltage or a burden? Imagine a man pulling a wagon up the hill. The voltage (V) is the man (120V). The () is in amperes, how much work he is doing to be way up the mountain (2amps) and the car your load (a motor) of a kind. Or maybe the man who brings a friend setting up the two of them (240V) with two to work together less work (1AMP) with the load the same (one stayEngine of some kind).
What does do a transformer? Transformers form a way control voltage. Take voltage and either step voltage down, step voltage up or isolating voltage in a range of one another. Why is it so important to have this tension. Take for example your local power company. It uses a step-voltage transformer to the power lines, the low currents generated type. Then, before your home or local measures that the voltage back down, the tensionInput is not excessive.
What parts make up a transformer? A transformer consists of three main components, the laminated iron core, primary and secondary windings. The primary winding is connected to the power of the transformer input) (input voltage. The secondary winding is connected when the power goes to) (the output voltage. The laminated core is the separation of primary and secondary windings from used no physical connection.
As transformers work?There are no moving parts of a transformer, but a transformer uses induction to power from the primary winding goes to the secondary winding. Understand simple way, what is it uses an inductive electromagnetic force to the tension, take the primary and move them to the secondary winding. We control induction with turn-ratio.
What is a turn ratio? A turn-ratio is the ratio between the primary and secondary. If there is 120v input of the transformerand 24 volts leaving the transformer. Our power would resign from his position with a 5 / 1 turn ratio. Simple math is used to calculate them, leaving voltage input / voltage of the transformer. With 120 / 24 have you 5 / 1 ration.
How do you assess the size of a transformer? You size a transformer for secondary winding of a transformer. The secondary winding is rated in VA (volts times current). An example would be that you have a 24v control circuit thats capacity 2amps. Would you describe your(24V), and multiply it by your maximum current (2amps), which would be 24 times 2, which corresponds to 48 or 48 VA. That means you would need for a transformer rated 48VA.
Thu Transformers may be serviced? No, no moving parts, there is no maintenance required. Once a transformer has gone bad, the show is generally on the primaries, she will have to be replaced. Some transformers are equipped with a Fuseable link, or a safety. When a transformer has been triggered orgone bad, it causes a general rule for finding a source of the problem. A bad transformer is never "the problem" just a symptom of the problem.
What are the different types of transformers? There are many kinds of transformers you see in the box, step up, step down, isolating, MULTI TAP and autotransformer. There is also another type, which is a three-phase transformer, referred to in this voltage transformer is greater access to a commercial building. As a generalRule is the most common type of transformer you see) is a step down transformer (control voltage.
What is the difference with these types of transformers? Step up transformers take the primary winding and the voltage step up to the secondary winding. Will step-down transformers take the primary step and the voltage across the secondary winding. Trenntransformatoren have the same voltage on the primary and secondary education. A multi-tap transformera step up or down transformer, multi-valve has either the primary or secondary. An autotransformer is a special type of transformer that does not follow common rules of transformers. It uses a continuous coil that is tapped to step down or step up to give function.
Transformers play an important role in AC powered systems. They are a way to control the tension. There is no need for transformer maintenance, although they are excellent indicators ofProblems. Understanding of these concepts and principles is key to troubleshooting and development of electrical circuits.
