Design of temperature acquisition system for three-phase transformer

The running state monitoring of the power transformer is the effective method to lower its failure rate. Three windings power transformer and site environment as monitoring object, a multi-channels temperature acquisition (TA) system is designed. It adopts blocking design, including temperature acquisition module and temperature data processing module and they communicate through CAN bus. The tests show, the temperature acquisition system can have exact acquisition, strong anti-jamming capability, far transferred distances and be suitable for large transformer field.
