The objective of this project is to preserve the domestic supply and power transformers from overload power. Drop in efficiency and overheating in secondary winding can be obviated with the help of this project.

The demand for electricity is increasing every day and frequent power cuts is causing many worriment in various areas like industries, hospitals and houses resulting in load increment hence overload. An alternate arrangement for power is a must. This project uses parallel transformers for load sharing at highest load on first transformer then automatically load transfer on second transformer.

Load sharing of the transformer is cinch with the help of this project theme and the life of the transformer is increased. The project is also used as a sustained power supply. If short circuit fault occurs, the transformer will be protected. A microcontroller of extraction is used. The output of microcontroller is given to the relay drive IC, which switches relevant relay to maintain uninterrupted supply to the load. The output shall be observed the current status, as to which derivation supplies the load is also displayed on an LCD.

The global system for mobile communication is used as it is accepted standard for digital communication and is helpful in sending message to authority via SMS whenever load is shared between the parallel transformers. Utility associations have enormous extent of money spend in transformers of all types, including distribution and power transformer. Operating, maintaining, and investigate all power transformers are not an easy work. In order to reduce burden on maintenance of such transformers a new perception has been discovered.

This project is mainly used to protect the transformer from getting deteriorated due to electrical disturbances or excessive load. The heat parameters are fed as base values, using a keypad to the Microcontroller and the output signal are provided to operate a relay by comparing the base values with the operating parameters. The application consists of a board of electronic components inclusive of a Microcontroller with programmable logic. It has been designed to work with high accuracy.

The heat parameters of the power transformer are fed to the Microcontroller as base values. By comparing the values the Microcontroller produces a trip signal which operates the relay and in turn the affinity between main transformer and parallel transformer is started and capacity is shared, thus protecting the power transformer from malfunctioning.

The main aim of the matter is Transformer sharing whenever load is increased for certain value and also sending this change in information to the respective authority via short message service SMS by using GSM Modem [1]. Drop in efficiency and overheating in secondary winding can be preserved with the help of this project. The demand for electricity is increasing everyday and frequent power cuts is causing many obstacles in various areas like industries, hospitals and houses resulting in load increment hence overload.

The output of microcontroller is given to the relay drive integrated circuit IC , which switches appropriate relay to maintain sustained supply to the load. The output shall be observed the current condition, as to which source supplies the load is also exhibit on an liquid crystal diode LCD. The global system for mobile GSM communication is used as it is accepted standard for digital communication and is helpful in sending message to authority via SMS whenever load is shared between the parallel transformers [2].

A number of literatures related to the topic of control systems and automation were reviewed and analyzed. Microcontroller The microcontroller incorporates all the features that are found in microprocessor. Since microcontrollers are dominant digital processors, the degree of regulation and programmability they provide significantly enhances the effectiveness of the application. Basically 8 bit specifies the width of data bus. This project works on the principle of Parallel operation of Transformers and have an arrangement of relays, loads, transformers, GSM modem, Microcontroller.

Two transformers are connected in parallel, in which one is working and the other one is in off condition. Whenever there will be a condition of overloading means load on transformer cross the specified value it will give relay the signal and relay will trip making transformer 2 in ON condition and load will be shared between two transformer thus decreasing the overload condition and saving the transformer and other electrical devices[6]. As SIM has the facility to read the received Message.

Relay: Relays are components which allow a low-power circuit to switch a relatively high current on and off. The current become zero it does capacity shedding of that particular zone. To make a relay operate, you have to pass a suitable pull-in and holding current through its energizing loop. In each case the coil has a resistance which will draw the right pull-in and holding currents when it is allied to that supply voltage. So basic idea is to choose a relay with a coil designed to operate from the supply voltage you are using for your control circuit capable of switching and then provide a relevant relay driver circuit so that low-power circuitry can control the current through the relays coil.

Lcd Display: When electric charge is applied they align to block the light entering through them, whereas when no-charge is applied they become transparent.

Light cursory through makes the desired images appear. This is the basic concept behind LCD displays. LCDs are most generally used because of their advantages over other display technologies. They are thin and flat and deplete very small amount of power compared to LED displays and cathode ray tubes CRTs [5].

If we run numbers of transformers in parallel, we can swap on only those transformers which will give the total demand by running nearer to its full capacity rating for that time. When load boost we can switch no one by one other transformer connected in parallel to accomplish the total excation. In this way we can run the system with maximum efficiency. By the help of microcontroller-based relay, protection of transformer is achieved very quickly and accurately.

This system overcomes the other drawbacks in the survive systems such as maintenance and response time [7]. All rights reserved by www. The same is true for unequal percent impedances and unequal kVA.

Circulating current only survive if the turn proportion do not match on each transformer. DeltaDelta to Delta-wye transformer paralleling should not be attempted [8]. If it is predicted that power exaction will be increased in future, there must be a provision of connecting transformers in system in coordinate to accomplish the extra demand because it is not economical from business point of view to install a bigger rated single transformer by anticipate the increased future demand as it is avoidable investment of money.

Again if future excation is reduction, transformers running in parallel can be evacuated from system to balance the capital investment and its return [9], [10]. Jadhav, and P. Gentry et.
