Electrical transformers are machines that transfer electricity from one circuit to another with changing voltage level but no frequency change. Nowadays, they are designed to use AC supply, which means that fluctuation in supply voltage is impacted by the fluctuation in the current. For this reason, an increase in current will bring about an increase in the voltage and vice versa.
Electrical transformers help improve safety and efficiency of power systems by raising and lowering voltage levels as and when needed. They are widely relied upon in a range of residential and industrial applications, primarily and perhaps most importantly in the distribution and regulation of power across long distances.
Transformers can be classified into different categories depending upon their end-use, construction, supply and purpose. They include purpose, supply, use, and supply, to mention a few. Some of the common applications of an electrical transformer include pumping stations, railways, industries, commercial establishments, windmills, and power generation units.
We can never conclude without mentioning the fact that all transformers share some common features regardless of their type. They include the frequency of input and output power being the same, and the fact that all transformers make use of electromagnetic induction laws.
Keep in mind the losses that do occur in transformers are smaller than those in other electrical devices. It includes copper loss which merely refers to power loss in the heat created by circulation of currents around the copper windings, considered the heaviest loss in transformers.
The second is copper loss which is merely eddy current and hysteresis losses caused by lagging of magnetic molecules in response to the alternating magnetic flux within the core. Luckily, most transformers are very efficient, delivering between 94% to 96% energy at full load. Very high-capacity transformers may deliver up to 98%, especially if they operate with constant voltage and frequency.
Take it upon yourself to do your homework to better understand what electrical transformers can do. Through this action, you won’t go through a lot merely because you want to buy the right electrical transformer for your needs.
