In many industries and M.S.M.E. there are cases of fire and the major cause is short circuit which mostly occurs due to moisture level increase in plant or increase in heat and temperature in the plant and circuits. So to overcome this we have developed a short circuit protection system using Arduino ,GSM module, heat sensor, temperature sensor, relay and alarm. It is easy to implement and can be used in various sectors and industries by changing certain parameters. Key Words: Arduino, DS18B20, GSM module, Industrial Automation, Sensor, Sim800A 1.INTRODUCTION Electric power is generated, transmitted and distributed through large interconnected power systems. The electric power is generated in various types of power plants. Then the voltage level of the power will be step up by the transformer before the power is transmitted. Since electric power is the product of voltage and current, high voltage is used in transmission in order to reduce the line currents then the power transmission losses is reduced that is copper loss. The primary objective of all power systems is to avoid the load shading. However, lightning or other natural events like wind and ice, physical accidents, equipment failure, and other unpredictable events may cause a short circuit between the phase wires of the transmission line or from the phase wires to ground, which is called a fault. Then the short circuit current is produced and the value of the short circuit current is very much greater than the normal operating current. So if there is a fault persists, there is a severe damage shown in the electrical equipments. In order to reduce such an accident, it is necessary to disconnect the faulted part from the healthy system as soon as possible. This is done by the circuit breaker and protective relay. 2. LITERATURE REVIEW KV Baoze Wei in his paper demonstrated that, in order to prevent working accidents by electrocution in high voltage systems, the main safety measure consists in connecting the earthing devices, on the both sides of working area. In any of these three cases, if the earthing devices are chosen and placed correctly, in the working area, as we expected, the drop voltage, is limited to a safety value. The worker on the console can touch one phase at a maximum distance of 2 m, and the voltage does not exceed 1 V, for 10 of the earth dispersion resistance.[1] Rakesh Maisuriya in simulation of short circuit condition and fault analysis in power system [2] From the discussion of IEEE 14 bus power system Mat-Lab model we can conclude that in an interconnected electrical power system if there is a fault occurs in any of the subsystem , all the system voltages and system currents are affected and must be improved otherwise it will creates fault of circuit parameters to other lines. This paper presents the Research literature work and the Review about the Short Circuit Analysis of a large Power System Network. Survey and lot of research papers have been presented for the improvement and new methods to analyze the Short Circuit Calculation in a Power System. The Aim of this Review Paper is to propose a calculation method in effortless technique for Short Circuit Analysis. The analysis of the most serious short-circuit fault provides a very high inrush current which is very dangerous for the system so to chop out this heavy current, a suitable step should be taken so that the dangerous effects of symmetrical faults can diminish and making the system more reliable. If we will not improve or disconnected faulty lines or area from healthy lines or area then huge crisis of power will be occurred, even blackouts. So instability, transient stability, fault analysis are very important in power network. Sharthak Munasib in Short-Circuit Protection for Low- Voltage DC Distribution Systems Based on Solid-State Circuit Breakers [8] The work presented in this thesis addressed some important issues regarding the short-circuit protection of low-voltage dc distribution systems. The following conclusions and contributions are drawn from the results presented and analyzed in the thesis: The RB-IGCT seems the best semiconductor device for implementing a 1- kVdc SSCB since it has the short-circuit capability of a thyristor (~ 3 kA), extremely low on-state voltage drop (~1.25 V) during normal SSCB operation, and blocks voltages in forward and reverse directions but conducts current only in the forward direction. It has low thermal resistance, assisted by double-sided cooling and hermetic sealing resulting from its hockey-puck, thyristor-type package. All of these attributes should result in increased efficiency, compactness and Compared to the standardized opening time of 35-40 ms during a fault for electromechanical circuit breakers, the SSCB containing RB-IGCT as the semiconductor switch
