Understanding Transformers

Before we move on to transformers, you need to know the basics of voltage. What is current and what is voltage? Picture a man carrying a cart uphill. The voltage (v), which is the man, 120v. The current (amps), which is the amount of work required to go up the hill, is the man (120v). Your load (a motor or some other kind) is the cart. You might have a friend who brings you 240v. With both of them working together, they do less work (1amp), and your load remains the exact same (amotor of some kind). In managing electricity infrastructure, all needs must be wise and with quality products. Then MGM Transformers can help to supply varying secondary voltages to externally connected loads. You can find quality electrical and lighting products at the MGM Transformer Company.

What is a transformer used for? Transformers are an electronic device that controls voltage. They measure voltage and can either reduce voltage or increase voltage. It is therefore vital to control voltage. Think about your local power provider. This transformer uses a stepup transformer to deliver high voltage to the electricity lines. However, it creates very low amperage. Steps are then taken to lower the voltage so that the voltage entering your home is not too high.

What are the components of a transformer A transformer consists of three components. The primary winding, primary winding and the laminated-iron core are the main components. The primary winding connects to the input voltage (power entering the transformer). The secondary connection is where the power is going to (output volt). The laminated Core is used to separate the primary and second windings.

What does a transformer do? A transformer does not contain moving parts. It uses induction instead to pass electricity from its primary winding to its secondary winding. The easiest way to understand induction is that it uses an electromagnetic force (or electromagnetic force) to pull the voltage from one winding and move it into the other winding. Induction is controlled with turn ratio.

What is a turning ratio? The relationship between the primary or secondary winding is known as a turn ratio. If the transformer had 120 volts entering it and 24 leaving it, the turn ratio would be 5/1. Our voltage would fall with a 5/1 rotation ratio. This can be calculated using simple math: voltage entering the transformer / voltage leaving it. You’d get 5/1 ration if you used 120 / 24,

How do size transformers? For secondary winding, a transformer must be sized. The secondary winding is rated by VA (volts x amperage). For example, a 24v control system with 2amps of capacity would work. Your voltage (24v), would be multiplied with the maximum amperage (2amps), which would result in 24 times 2 or 48 va. This would mean that you need a transformer with 48va ratings.

Do transformers require maintenance? No. There is no maintenance necessary because there are no moving components. If a transformer goes bad, which can generally show on the primary wounds, it must be replaced. Some transformers are equipped with a safety fuse or link. If a transformer is tripped or goes bad, it is best to locate the source. A bad transformer does not necessarily mean that the problem is solved. It may be a sign that something else is wrong.
