Referring to FIG. 1, illustrated is a block diagram of architecture of the electronic device 100, in accordance with an embodiment of the present disclosure. As shown, the electronic device 100 having the surge-voltage protection circuit 102 comprising the input slot 104; the detachable input terminal element 106 configured to be received by the input slot 104; the first locking mechanism 108 configured to establish the appropriate connection between the input slot 104 and the detachable input terminal element 106; the output slot 110; the detachable output terminal element 112 configured to be received by the output slot 110; the second locking mechanism 114 configured to establish the appropriate connection between the output slot 110 and the detachable output terminal element 112; the power supply slot 116; the detachable power supply terminal element 118 configured to be received by the power supply slot 116; the third locking mechanism 120 configured to establish the appropriate connection between the power supply slot 116 and the detachable power supply terminal element 118; and the indicator 122.
In an embodiment, the electronic device 100 refers to a given device responsible for controlling flow of electrons for performing a particular operation. Examples of the electronic device 100 includes, but are not limited to a transducer, a transmitter and the like. In an example, a plurality of electronic devices can be grouped together in a manner that they form integrated circuits for example such as a microprocessor, a microcontroller and so forth.
In an embodiment, the term "surge-voltage" refers to a transient wave of voltage in an electric circuit, wherein the transient wave of voltage are overvoltage spikes in a supply-voltage for a substantially small duration. Furthermore, such surge-voltages may damage the electronic device 100 within any home, commercial building, industrial or manufacturing facility. Moreover, such surge-voltages may also damage an internal circuitry of the electric circuit. In an example, such surge-voltages may also damage a control panel of the electric circuit. However, it is important to provide protection to the electronic device 100 from the surge-voltage. Therefore, the electronic device 100 having the surge-voltage protection circuit 102 is employed to protect the electronic device 100 from the surge-voltage.
In an embodiment, the surge-voltage protection circuit 102 is configured to shut-off the electronic device 100 when a value of the supply-voltage for the electronic device 100 exceeds a predefined-value. Notably, the predefined-value of the supply-voltage is 300V AC. The term "predefined-value" refers to a given value of the supply-voltage exceeding which the electronic device stops functioning (namely, shuts-off). Notably, the surge-voltage protection circuit 102 is configured to compare the value of the supply-voltage for the electronic device 100 with the predefined-value of the supply-voltage. Therefore, in such a case, working of the surge-voltage protection circuit 102 can be considered to be similar as working of a voltage comparator.
In an embodiment, the surge-voltage protection circuit 102 is configured to produce an output signal based upon the comparison of the value of the supply-voltage for the electronic device 100 with the predefined-value of the supply-voltage. Notably, the supply-voltage for the electronic device 100 relates to the power supply provided to the electronic device 100 for performing various operations. In an example, the value of the supply-voltage for the electronic device 100 may lie within a range of 90 to 270V AC. In such an example, the value of the supply-voltage for the electronic device 100 may be 90V AC, 95V AC, 100V AC, 110V AC, 150V AC, 170V AC, 210V AC, 220V AC, 250V AC and 270V AC.
In an embodiment, the surge-voltage protection circuit 102 is implemented by a way of one of: an operational amplifier, a comparator, a dedicated comparator integrated circuit.
In an embodiment, the surge-voltage protection circuit 102 is implemented by a way of the comparator. In an example, the value of the supply-voltage for the electronic device 100 may be lower than the predefined-value of the supply-voltage and thus, lies within an acceptable range (for example, such as 90 to 270V AC) of the value of the supply-voltage. In such an example, the surge-voltage protection circuit 102 generates the output signal in a manner that the electronic device 100 operates normally. In another example, the value of the supply-voltage for the electronic device 100 may be higher than the predefined-value of the supply-voltage resulting in a high surge-voltage. In such an example, the surge-voltage protection circuit 102 generates the output signal in a manner that the electronic device 100 shuts-off, thereby protecting the electronic device 100 from any damage due to the high input surge-voltage. Furthermore, in such an example, the internal circuitry of the electric circuit is protected from the damages due to the high surge-voltage in addition to the electronic device 100.
In an embodiment, the surge-voltage protection circuit 102 is implemented by a way of the operational amplifier (herein after referred to as "Op-Amp"). Generally, the Op-Amp is configured to compare two analog input signals and generate an analog output signal. Furthermore, a diode or a transistor is added to the Op-Amp circuit in order to implement the Op-Amp as the voltage comparator. Furthermore, the Op-Amp comprises a positive input terminal and a negative input terminal. In an example, the supply-voltage 'Vin' (for the electronic device 100) may be connected to the positive terminal of the Op-Amp and the predefined supply-voltage 'Vref' may be connected to the negative terminal of the Op-Amp. In such an example, when the supply-voltage 'Vin' is lower than the predefined supply-voltage 'Vref'; the output signal 'Vout' is generated, thereby allowing the electronic device 100 to perform various operations. Furthermore, in such an example, when the supply-voltage 'Vin' is higher than the predefined supply-voltage 'Vref', the output signal 'Vout' is generated, thereby allowing the electronic device 100 to stop functioning (namely, shuts-off).
In another example, the supply-voltage 'Vin' may be connected to the negative terminal of the Op-amp and the predefined supply-voltage 'Vref' may be connected to the positive terminal of the Op-amp. In such an example, when the supply-voltage 'Vin' is lesser than the predefined supply-voltage 'Vref', the output signal 'Vout' is generated, thereby allowing the electronic device 100 to stop functioning. Furthermore, in such an example, when the supply-voltage 'Vin' is lower than the predefined supply-voltage 'Vref', the output signal 'Vout' is generated, thereby allowing the electronic device 100 to perform various operations.
In an embodiment, the surge-voltage protection circuit 102 may be implemented by a way of dedicated comparator integrated circuit (herein after referred to as "dedicated comparator IC") employing diodes or transistors. In such a case, the dedicated comparator IC is configured to compare two analog input signals and produce a digital output signal. Notably, the dedicated comparator IC compares the value of the supply-voltage for the electronic device 100 and the predefined-value of the supply-voltage and generates the digital output signal. Furthermore, in such a case, the digital output signal generates a high signal, or a low signal based upon the result of the comparison of the said supply-voltages by the dedicated comparator IC. Moreover, the digital output signal is transmitted to the electronic device 100, via a digital to analog convertor, in a manner that the electronic device 100 will stop functioning (namely, shuts-off) when the value of the supply-voltage for the electronic device 100 exceeds the predefined-value of the supply-voltage.

In an embodiment, the electronic device 100 comprises the indicator 122 configured to provide an indication signal when the detachable input terminal element 106, either establishes or fails to establish the appropriate connection with the input slot 104. Notably, the indicator 122 indicates information related to appropriate connection of the detachable input terminal element 106 with the input slot 104.
In an embodiment, the indicator 122 is implemented by way of a light indicator for example such as a light emitting diode (LED). More particularly, the indicator 122 (herein after referred to as "LED indicator") will act as an overseer, thereby indicating a state of the detachable input terminal element 106. Notably, the states of the detachable input terminal element 106 can be one of: open, closed, partially-closed. The open state of the detachable input terminal element 106 refers to a given state of the detachable input terminal element 106 when the detachable input terminal element 106 is not placed within the input slot 104, thereby no connection is established therein. The partially-closed state of the detachable input terminal element 106 refers to a given state of the detachable input terminal element 106 when the detachable input terminal element 106 is placed within the input slot 104, wherein the detachable input terminal element 106 fails to establish the appropriate connection with the input slot 104. The closed state of the detachable input terminal element 106 refers to a given state of the detachable input terminal element 106 when the detachable input terminal element 106 is placed within the input slot 104, wherein the detachable input terminal element 106 establishes the appropriate connection with the input slot 104.
In an embodiment, the LED indicator 122 is configured to generate the indication signal when the detachable input terminal element 106 fails to establish the appropriate connection with the input slot 104. In such a case, when the detachable input terminal element 106 is in open or partially-closed state, the LED indicator 122 blinks intermittently thereby, indicating that the detachable input terminal element 106 fails to establish the appropriate connection with the input slot 104. Moreover, the intermittent blinking of the LED indicator 122 acts as a visual cue to signify that the detachable input terminal element 106 is in open or partially-closed state. Additionally, the LED indicator 122 is configured to prevent generation of the indication signal when the detachable input terminal element 106 establishes the appropriate connection with the input slot 104. In such a case, when the detachable input terminal element 106 is in closed state, the LED indicator 122 stops blinking, thereby indicating that the detachable input terminal element 106 establishes the appropriate connection with the input slot 104. Furthermore, in such a case, the LED indicator 122 will be in a switch-off state signifying that it is stable when the appropriate connection is established.
Alternatively, in an embodiment, the LED indicator 122 is configured to generate the indication signal when the detachable input terminal element 106 establishes the appropriate connection with the input slot 104. In such a case, when the detachable input terminal element 106 is in closed state, the LED indicator 116 blinks intermittently thereby, indicating that the detachable input terminal element 106 establishes the appropriate connection with the input slot 104. Moreover, the intermittent blinking of the LED indicator 122 acts as a visual cue to signify that the detachable input terminal element 106 is in closed state. Additionally, the LED indicator 122 is configured to prevent generation of the indication signal when the detachable input terminal element 106 fails to establish the appropriate connection with the input slot 104. In such a case, when the detachable input terminal element 106 is in open or partially-closed state, the LED indicator 122 stops blinking, thereby indicating that the detachable input terminal element 106 fails to establish the appropriate connection with the input slot 104. Furthermore, in such a case, the LED indicator 122 will be in a switch-off state signifying that it is stable when the appropriate connection is not established.
In an embodiment, the electronic device 100 comprises another LED indicator, wherein the another LED indicator is configured to generate the indication signal when, in operation, the power supply is being provided to the electronic device 100. In such a case, the another LED indicator glows when the power supply is being provided to the electronic device 100. Additionally, the another LED indicator is configured to prevent generation the indication signal when, in operation, the power supply is not provided to the electronic device 100. In such a case, the another LED indicator will be in a switch-off state when the supply-voltage is not provided to the electronic device 100.

The detachable input, output and power supply terminal elements 106, 112 and 118 are configured to be received by only the input, output and power supply slots 104, 110 and 116, respectively. Furthermore, as shown, the first input locking part 108A arranged in the input slot 104; and the second input locking part 108B arranged on the detachable input terminal element 106, wherein the first input locking part 108A aligns with the second input locking part 108B to establish appropriate connection between the input slot 104 and the detachable input terminal element 106. Moreover, the first output locking part 114A arranged in the output slot 110; and the second output locking part 114B arranged on the detachable output terminal element 112, wherein the first output locking part 114A aligns with the second output locking part 114B to establish appropriate connection between the output slot 110 and the detachable output terminal element 112. Furthermore, the first power supply locking part 120A arranged in the power supply slot 116; and the second power supply locking part 120B arranged on the detachable power supply terminal element 118, wherein the first power supply locking part 120A aligns with the second power supply locking part 120B to establish appropriate connection between the power supply slot 116 and the detachable power supply terminal element 118.
In an embodiment, the electronic device 100 is the transducer. The transducer is a device that converts one form of energy into another form of energy. More particularly, the transducers are employed to convert resistance to electronic energy.
In an embodiment, the transducer is configured to transmit temperature related information of winding and/or oil of a transformer to a remote location. Beneficially, the temperature of winding and/or oil of the transformer is to be determined in order to protect transformer from damage. Generally, the temperature of winding and/or oil of the transformer should not increase beyond a certain limit in order to maintain its safety and productivity. In such a case, a first resistance-temperature-detector (hereafter referred to as "RTDo") is employed to determine temperature of winding of the transformer and a second resistance-temperature-detector (hereafter referred to as "RTDw") is employed to determine temperature of the oil within the transformer. In such a case, the detachable input terminal element 106 of the transducer is coupled to the resistance-temperature-detector. Therefore, the input of the transducer is in the form of resistance (in ohms). In an example, resistance-temperature-detector is a PT100 RTD sensor. The transducer is configured to convert resistance into current. Notably, the temperature information of the winding and/or oil of transformer is calibrated, thereby generating a current signal in order to indicate the corresponding temperature of the winding and/or oil of transformer. The output of the transducer is in the form of current. In an example, value of the current may lie within a range of 4-20 milliampere. In such a case, the detachable output terminal element 106 of the transducer is coupled to temperature indicator.
In an embodiment, the transducer is configured to transmit temperature related information of winding and/or oil of a transformer to a remote location. In such a case, the information can be transmitted via a supervisory control and data acquisition system (herein after referred to as "SCADA"). The SCADA is a system of software and hardware elements that allows industrial organizations to: control industrial processes locally or at remote locations; monitor, gather, and process real-time data; record events into a log file and directly interact with devices such as sensors, valves, pumps, motors, and more through human-machine interface (HMI) software.
In an example, a power system may employ a plurality of transformers to generate electricity. In such a case, the temperature of winding and/or oil of each transformer of the plurality of transformers is to be determined in order to protect the plurality of transformer from damage. In such an example, a plurality of transducers may be employed to transmit temperature related information of winding and/or oil of each of the transformer of the plurality of transformers from plurality of resistance-temperature-detectors to a plurality of temperature indicators. Therefore, protecting the power system in addition to the plurality of transformers from any damage caused due to increase in the temperature of winding and/or oil of the transformer beyond a certain limit. In such a case, it is important to protect the transducer from the high surge-voltages in order to maintain safety and productivity of the power system and its components. Therefore, the surge-voltage protection circuit is implemented by a way of Op-Amp within the transducer. In such a case, the Op-Amp is configured to shut-off the transducer when the value of the supply-voltage for the transducer exceeds the predefined-value of 300V AC. As a result, the transducer will go to sleep-mode, thereby protecting the power system in addition to the plurality of transformers.

Embodiments of the present disclosure are described for the predefined-value of the supply-voltage (for the electronic device 100) as 300V AC. However, a person ordinarily skilled in the art would appreciate that, for the predefined-value of the supply-voltage lesser than 300V AC or greater than 300V AC, the present disclosure works well.
