摘要
Power transformer fault is the major issue in power conversion system, as most of the fault measured in transformer can be cleared as offline which leads to a power shutdown, affects continuously operated loads and also routine monitoring is essential. Online monitoring system is designed and developed to deliver the perpetual power to the beneficiaries and the faults are rectified onsite. This invention enables regular sensing temperature variations in the transformer oil and gases evolved due to faults using temperature and gas sensors, fault features are extracted by DGA (Dissolved Gas Analysis) method using these features the fault types are analyzed by EA (Evolutionary Algorithm) and finally fault rectification is performed by the control signals from the controller circuit to provide continuous power supply. The application of this online monitoring system is to provide efficient energy conversion that avoids life hazard and ensures increased productivity in the manufacturing establishments.
