With the various kinds of transformers available in the market, each supporting different applications, power transformers in India are the most popular types of transformers used. These transformers are highly efficient in transmitting high voltage levels at loads above 33kv. In fact, they perform their best at 100% load! This quality of providing maximum efficiency has resulted in power transformers being used in transmission networks, transmission substations, and power generation stations. These power transformers are further categorized into step-up and step-down transformers to increase or decrease the voltage levels as required.
What are auto-transformers?
Auto transformers are electrical transformers having only a single winding; thus the single coil acting alone, without any kind of automatic mechanism like in other transformers. In fact, the single coil itself plays the role of both primary and secondary winding’s, with one end acting as primary, and the other end acting as the secondary. In this way, auto-transformers have the benefit of being smaller, lighter, and cheaper than other double winding transformers; but with the disadvantage of not providing isolation between the primary and secondary circuits.
A tap changer is a device fitted to a transformer to regulate the output voltage to the required level. This is done by changing the turn ratios of the transformers by connecting to a number of access points known as ‘taps’ along either the primary or secondary winding. These tap changers are generally placed on low-current high-voltage transformers to minimize the current load during operation. Tap changers exist as two types – no load tap changers, and on load tap changers.
Both step-up and step-down transformers are constructed to change the AC voltage to supply power to various types of residential and commercial electrical applications. The only difference between the two is that step-up transformers increase the voltage from primary to secondary, while step-down transformers decrease the voltage.
Although for a layman, transformers and inductors seem to be the same in appearance and construction, but those in the field dealing with these equipment know that the two devices are similar, but not the same. They differ in applications, and also have their own unique design and construction. This blog will give you detailed information about these differences so that you are no more in the belief of the myth of both transformers and inductors being the same. After reading the blog, when you understand the difference between the two, and decide on using any one of them for your application, you can approach Miracle Electronics, the leading transformer and inductor coil manufacturer in India, who can serve almost every electronic purpose for your varied applications.
Home and office appliances seem to be admired by users when they can offer maximum performance while maintaining the lowest possible power consumption. This is possible when switched mode power supplies (SMPS) are used that can convert power using switching devices that are turned on and off at high frequencies, and inductors/capacitors to supply power when the switching device is in a non-conduction state. Thus, you can create an efficient power output with an SMPS transformer. And, when you purchase one from Miracle Electronics, the leading SMPS transformer manufacturer in India, you can ensure its robustness and reliability.
Switch Mode Power Supply (SMPS) transformers are flexible and used in a variety of industries like aerospace, biomedical, telecommunications, and automation controls. The major applications for these transformers include converters, inverters, switching regulators, low power isolation power supplies, high Q filters, and RFI filters. With so many applications using these transformers, it is important that you test your transformers periodically so as to avoid any faults or breakdowns.
