We need to establish some basic principles before the expansion of the voltage transformers. What is the current, voltage or a burden? Imagine a man, a trailer, a car uphill. The voltage (v) is the man (120V). The current (amps) is the amount of work he does to make up the hill (2amps) and the machine is your load (motor of some sort). Or perhaps the creation of man brings a friend of two of them (240) with two work together, work less (1 Amp) with the load remains the same (one motorsome sort).
What makes a transformer do? Form a control voltage transformers so. Take a step down the power and voltage, voltage step-up voltage or isolate within another. So, why is it so important to check the voltage. Take for example the local power company. It used to be a step transformer high-voltage power lines, which creates low amperage. Then, before your home or local measures the voltage back, so that the tension is not placedexaggerated.
What parts make up a transformer? A transformer consists of three main components, the laminated iron core, primary and secondary windings. The primary is the power entering the transformer (input voltage) is connected. The secondary winding is connected when the power goes to (voltage output). The core laminate is used to separate primary and secondary windings of a physical connection.
As transformers work? There are no moving partsa transformer used in place of a current transformer to induce the primary to the secondary winding step. Simply to understand, what is that it uses electromagnetic induction to take a power cord from the primary coil and move it to the secondary. We control induction coil ratio.
What is the turns ratio? A turn-ratio is the ratio between primary and secondary. If input and 24 volt transformer 120v to leave theTransformer. Our power would resign with a 5 / 1 turns ratio. Simple math problem is used to calculate this, the input voltage / output voltage of the transformer. 120 / 24 you would need 5 / 1 ration.
How do you size a transformer? He cuts a secondary winding of the transformer for a transformer. The secondary winding is rated in VA (volt ampere times). An example would be a 24v control circuit that has the ability 2amps. She would your voltage (24V) and multiplyfrom their maximum current (2amps), which is 24 times, 2, the same 48 or 48 VA. That means you would need a 48va transformer rated for.
Transformers Gio to keep? No, there are no moving parts, no maintenance. Once a transformer went bad, the show is usually the primary windings, it must be replaced. Some transformers are casting on a link or a title. When a transformer is tripped or is defective, there is a general rule for researcha source is the cause of the problem. A transformer is never wrong "problem" is 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, and Multi-tap auto-transformers. There is also another type, which is a three-phase transformer, transformer, this is more tension in a commercial building. As a general rule, the most common type of transformer you will see is astep-down transformer (voltage control).
What is the difference in these types of transformers? Step up transformers take the primary step for the secondary winding voltage. Step down transformers take the primary winding and the voltage drop across the secondary. Isolation transformers have the same voltage to the primary and secondary. A multi-tap transformer is a step up or down transformer has multiple outputs, either in primary orSecondary winding. An autotransformer is a special type of transformer that does not follow the common rules of transformers. It uses a continuous coil used to provide a step back or step-ups.
Transformers play a key role in AC-powered systems. It is a way to control stress. No maintenance is required to transformer, even though they are excellent indicators of problems. Do you understand these concepts and principles is the key to solving problems and electrical designCircuits.
