摘要：This project deals with the monitoring and control of cooling system of a transformer using automation. Probability of faults on power transformer is undoubtedly more and hence automatic protection is absolutely necessary. Temperature sensor is used to sense the temperature of the power transformer that provides the value of temperature. Output from the sensor is fed to the Programmable Logic Controller (PLC). A PLC is a digitally operating system designed for use in an industrial environment, which uses a programmable memory for its internal operation of user-oriented instructions and for implementing specific function such as logic, sequencing, timing, counting and arithmetic. By introducing PLC into action the process becomes more flexible, reliable and PC friendly. HMI activities are availed to have better visualization of the process and control. Trouble shooting experience becomes easier now compared to existing technology.
