Transformer Fault Detection and Protection System (original) (raw)
In this project all designs are constructed based on two major systems. One is RTD (Resistance Temperature Detector) and another is PLC (Programmable Logic Controller). Resistance Temperature Detector (RTD) is temperature sensors that provide the variable resistance value as its temperature changes. It gives the output of the value of resistance corresponding to the transformer winding temperature to PLC. A programmable Logic Controller (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. PLC has a program on the microprocessor then microprocessor processing the program on base of RTD output and PLC gives command to start the cooling fan to decrease the temperature. If temperature is increasing over the safety limit than PLC disconnects the incoming power of the tra...
