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.
While earlier agriculture had everything done manually, today it has transformed into a high-tech sector with a variety of magnetic being used for farming, tilling, and harvesting. One of the equipment that helps in a major way in this industry is the transformer. These equipment are designed to provide sufficient power to support various agricultural applications. There are various types of transformers available in the market, out of which three are majorly used in the agricultural industry, namely power transformers, auto transformers, and high voltage transformers.
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 current transformer is a type of transformer that measures alternating current (AC) by producing an AC in its secondary which proportional to the AC in its primary. When the current to be measured or the system voltage of the circuit is too high, current transformers are used to provide an isolated lower current in its secondary, which is proportional to the current in the primary circuit. The induced secondary current produced is then suitable to measure instruments and process electronic equipment. This is the reason why current transformers are popularly used for metering and protective relays in the electrical power industry.
Need to install a new transformer or replace an existing one? Just come up to Miracle Electronics, the leading transformer manufacturer in India and you won’t have to worry about installing newer transformers for a long time again! Here are some essentials you need to know about transformers and their installation.
Transformers are used at all levels of the industrial infrastructure, right from power generating stations up till the customer facilities; thus they play a very significant role in our lives. The oil present in transformers performs the functions of insulating as well as cooling. Therefore, for secure functioning of a transformer, the dielectric quality of the oil needs to be maintained. As the oil ages, it deteriorates in quality, which is why the oil should be tested periodically.
Transformers have a cylindrical tank, known as the conservator tank, mounted on the roof of its main tank to provide adequate space for expansion of oil within the transformer. When the temperature rises, the volume of oil inside the transformer also increases; thus, it is this conservator tank that acts as a reservoir for the expanded oil. Let us learn all about the construction, working and benefits of a conservator tank in detail.
