| Popis: | This manuscript focuses on Direct Monitoring & Control of Transformer Temperature in order to avoid its Breakdown Using FOS (fiber optic sensor). Although there are various reasons for failure of transformer operation but mainly it is due to conductor loss and hysteresis losses which causes temperature rise in the internal structures of the transformer leading to burning of windings. A system for monitoring the temperature of transformers is required. Existing sensors cannot be used for monitoring the temperature of transformers because they are sensitive to electrical signals and can cause sparking which can trigger fire since there is oil in transformers cooling coils. Distributed FOS based on microbend is simulated on MATLAB7.5 in order to check the effectiveness of this sensor. Results in the form of graphs i.e., intensity modulation vs. the temperature has been shown in the manuscript. |
