The function of a transformer is to transform electrical circuit from one another through a inductive coupled conductor. Modern transformers are low on losses and these are used to transmit high power across long distance in the most economically viable manner. The origin of transformer is traced down to 1831 by Faraday and Joseph Henry. Though, the first transformer was invented by Rev. Nicholas Callan of Maynooth College, Ireland in the year 1836. This was called the induction coil.
Functions of constant voltage transformer
Whenever an increase in the voltage is required transformer is used. It is available in single phase and three phases. It provides electrical isolation and power distribution. In a high voltage transformer, the power, current and voltage ratings are the highest and it falls under the ambit of electrical transformer.
The transformer helps the electrical energy to be transmitted to homes, offices and industries direct from the power plants. Modern industries have their private in built transformers construction. In this system oil is used to move the heat away from the coil by making the environment cooler insulating the coil from itself. During this process the oil used should not evaporate and produce gases, hence mineral oil is used for this purpose.
Classification of transformers
Current transformer produces perpendicular flow of current from the primary circuit. The current transformer is controlled with the help of single primary turn coil depending on the number of turns of wire wound on the coil. To make sure the current transformer is working properly it is important to ensure that the transformer is not removed when the current is in motion. In this type of transformer, the output and the quality are superior.
Electric transformers are used to transfer alternating current from one circuit to another through electromagnetic induction. In the simplest form, it consists of two wire coils insulated from one another to change the current from a coil known as the primary to produce change of voltage in the secondary coil. In this case fly back is made used to produce high transformer voltage at high frequency and this is termed as output transformer. Similarly, Fail safe mechanism and the fly back operating frequency is lighter and smaller when compared to other transformers.
Most low cost transformer manufacturers construct the transformer from different coil combinations. The basic among them is a two wire coil, a primary and secondary insulated from one another. Another name for line input transformer is high voltage transformer and it functions at high frequency using fly back.
Improving the electrical grid performance is the need of the hour and all efforts are taken in this direction. The Constant Voltage Transformer dealer in Chennai aims at maximizing efforts in meeting the rapid growing demands of the society. With the increase in digital communication, environment norms, reliability regulations, reliance on secondary power and adapting to smart metering is change the phase of electricity consumption in the modern society. The transformers made use in the power transmission process is seen as a potential for immediate benefits for enhanced energy security. Moreover it reduces emission of greenhouse gases and improves the quality of air giving rise to greater grid utilization.
To maintain sustainable performance it is important to take care of vital statistics like vacuum level, pressure, temperature, oil level, water content in oil and the hydrogen gas percentage. Apart from this system parameters like loss of power, cooling fan status, input and output voltages, ambient temperature and output current are monitored and information is gathered real time to enhance the performance of the transformer.
The grid needs are addressed by improving the performance of the transformer. It includes improver energy security and cutting down on harmful emission gases. At regular intervals the oil samples need to be collected from the transformer to test for dissolved gases. It helps to mitigate risks by improving the life of the transformer and also cuts down on downtime.
The present day transformers are light weight, efficient, reliable and provide uninterrupted power. Transformers play a vital role in improving the secondary side of the smart power grid. The reason transformer is used is to protected from high voltage break downs. The power distribution is streamlines and downtime is minimized to a greater extent with the help of transformer systems.
