Most industries and organizations depend on massive machinery and equipment. The electrical transformers provide these industries and facilities with a significant voltage that holds critical importance in various industries.
From substations and power plants to automotive, biochemical, engineering, and telecommunications sectors, diversified appliances using electrical transformers can be seen.
What Are Electrical Transformers?
Electrical transformers are electric equipment, which is used for transferring specific amounts of electrical energy from any single circuit to another, utilizing the method of electromagnetic induction. Such transformers are most widely used to raise or lower circuit voltage levels.
Usually, electrical transformers consist of three main parts, namely:
- Primary winding
- Secondary winding, and
- Magnetic core.
The primary windings are made up of various turns connected to the primary power source, where the magnetic core of the electrical transformers allows the magnetic flux to pass through the secondary winding connection and causing EMF. The secondary windings of the electrical transformers have the voltage levels used for supplying energy to other circuits. The industrial sector needs to ensure proper, safe, and careful use of power to avoid unnecessary power problems.
What Is An Electrical Transformer’s Function?
Electrical transformers’ basic function is to initiate a step up or down function for alternating the voltage levels by retaining power at an equivalent level and changing the frequency. The number of circuit turns in the main and secondary windings determines to raise or decrease the voltage levels.
Usually, electrical transformers used on the generator side (increase the voltage level) are called step-up transformers, whereas the transformers used at the load end (decrease the voltage level) are called step-down transformers.
Apart from the ways mentioned above, you will find a range of electrical transformers constructed in a manner where both ends have the same numbers. Such designs are not made to support a change in the voltage levels and are intended for safety purposes.
Points To Remember Before Buying Electrical Transformers
Before deciding on investing in electrical transformers, it is recommended that you consult a certified electrical expert and understand your business requirements. Doing so confirms you make an informed decision and find the best suitable solution.
Power Supply [Phase and Sectors]
Begin with determining whether you need a single-phase or a three-phase (3-Phase) transformer. Simple equipment and household electrical appliances require single-phase electrical transformers, and commercial manufacturing applications needing three-phase electrical transformers.
Before choosing a transformer, it is necessary to note the load specifications. Suppose constant heavy loads are to be sustained and managed. In that case, electrical transformers equipped with improved levels of power should be chosen.
You need to locate the input voltage supply and check the voltage specifications for different devices.
The electrical transformers’ frequency is usually 50 Hz since the power supply for differentiated power-based machines or electrical applications is the same. However, in certain countries such as the U.S., the transformers are configured to allow a frequency of 60 Hz depending on their power supply systems.
Location or Position
You can mount electrical transformers both indoors and outdoors, depending on the type of transformer you chose for your facility. Depending on the distance, application, and other position factors, you need to choose the right transformer.
Objective Of Specific Electrical Transformers
Another crucial aspect that demands attention is the function of the transformer. Electrical transformers may be used for a range of purposes. Your decision should be based on the desired results expected from the transformer. For example: Do you want to use electrical transformers for functions such as isolation, achieving the K factor, or do you want it to function as a self-transformer.
Facility Setting Where Transformers Are Installed
The various electrical transformers’ requirements differ depending on the setting in which you plan to use them. If your transformer is designated to be fixed in an open space, which means it probably will be exposed to harsh weather conditions, including rain, wind, dust, and the sun; so, investing in a cooled oil or a liquid-filled transformer as it would protect the metallic windings from the usual wear-and-tear as well as damaging effects of the weather.
You need to realize how you’d like the electrical transformer is to be programmed. Then you can look for options to find the best transformer yourself. Remember that the power transformer manufacturers provide specialized cables and electrical transformers, ensuring faster communication and interconnections. Don’t forget to seek expert guidance and get the best options to enable the highest possible business-returns!
