    2.2 Configuration of Transformer health monitoring system:
    The framework structure speaks to the association of the individual parts.

    The framework is orchestrated so that the yields from sensors-Current transformer(sense the measure of current), Temperature sensor(sense the temperature),Potential transformer(sense the voltage) are given to the controller raspberry pi. The voltage which is detected will be more than the working voltage of the controller. This may harm the controller. So the utilization of transfer limits this harm by changing over the voltage which is detected by the sensor into a proper incentive for the microcontroller to work efficiently.The ADC is utilized to peruse the parameters and the qualities get put away in the memory for preparing. The GSM is interfaced with the small scale controller and it downloads SMS messages which contain the data identified with the transformer parameters and status. At that point this SMS is sent to checking focuses containing data about parameters estimation of the dissemination transformers. In this way the game plan is designed.

    Current Transformer:
    A present transformer (CT) is a sort of transformer that is utilized to quantify exchanging current (AC). It delivers a current in its optional which is corresponding to the current in its essential.
    Current transformers, alongside voltage or potential transformers, are instrument transformers. Instrument transformers scale the vast estimations of voltage or current to little, institutionalized qualities that are anything but difficult to deal with for instruments and defensive transfers. The instrument transformers seclude estimation or security circuits from the high voltage of the essential framework. A present transformer gives an auxiliary current that is precisely corresponding to the current streaming in its essential. The present transformer displays a unimportant load to the essential circuit.
    Flow transformers are the flow detecting units of the power framework and are utilized at producing stations, electrical substations, and in modern and business electric power dissemination.

    In view of the capacity development, it can likewise be delegated pursues:
    Bar Type: This sort comprises of a bar of reasonable size and material framing a fundamental piece of the transformer.
    Wound Type: This sort has an essential twisting of mineral than one full turn twisted over the center.
    Window Type: This sort has no essential winding. The auxiliary breeze of the CT is put around the current streaming conductor. The attractive electric field made by flow coursing through the conveyor initiates flow in the auxiliary winding, which is utilized for estimation.RELAY:
    Transfers are switches that open and close circuits electromechanically or electronically. Transfers control one electrical circuit by opening and shutting contacts in another circuit. As hand-off charts appear, when a hand-off contact is ordinarily open (NO), there is an open contact when the hand-off isn’t invigorated. At the point when a transfer contact is Normally Closed (NC), there is a shut contact when the hand-off isn’t stimulated. In either case, applying electrical flow to the contacts will change their state.
    Transfers are for the most part used to switch littler flows in a control circuit and don’t for the most part control devouring gadgets with the exception of little engines and Solenoids that draw low amps. In any case, transfers can “control” bigger voltages and amperes by having an enhancing impact in light of the fact that a little voltage connected to a transfers loop can result in an expansive voltage being exchanged by the contacts.

    Defensive transfers can anticipate hardware harm by recognizing electrical irregularities, including overcurrent, inclination, over-burdens and turn around flows. What’s more, transfers are additionally generally used to switch beginning loops, warming components, pilot lights and perceptible cautions.

    GSM/GPRS module is used to establish communication between a computer and a GSM-GPRS system. Global System for Mobile communication (GSM) is an architecture used for mobile communication in most of the countries. Global Packet Radio Service (GPRS) is an extension of GSM that enables higher data transmission rate. GSM/GPRS module consists of a GSM/GPRS modem assembled together with power supply circuit and communication interfaces (like RS-232, USB, etc) for computer. GSM/GPRS MODEM is a class of wireless MODEM devices that are designed for communication of a computer with the GSM and GPRS network. It requires aSIM (Subscriber Identity Module) card just like mobile phones to activate communication with the network. Also they have IMEI (International Mobile Equipment Identity) number similar to mobile phones for their identification. A GSM/GPRS MODEM can perform the following operations:
    1.      Receive, send or delete SMS messages in a SIM.

    2.      Read, add, search phonebook entries of the SIM.

    3.      Make, Receive, or reject a voice call.

    The MODEM needs AT commands, for interacting with processor or controller, which are communicated through serial communication. These commands are sent by the controller/processor. The MODEM sends back a result after it receives a command. Different AT commands supported by the MODEM can be sent by the processor/controller/computer to interact with the GSM and GPRS cellular network.
