AN INTELLIGENT METHOD FOR LOAD SHARING OF TRANSFORMERS WITH TEMPERATURE MONITORING ANDAUTOMATIC CORRECTION OF POWER FACTOR

Distribution transformers are an important part of power system which distributes power to the low-voltage users directly, and its operation condition is important for the entire distribution network operation.However, their life is significantly reduced if they are subjected to overloading and overtemperature resulting in unexpected failures and loss of supply to a large number of customers thus effecting system reliability.Protection against fault in power systems is very essential and vital for its reliable perfomance..Thus to protect the transformers from overloads and over temperature, the concept of load sharing has been proposed, wherein, automatic load sharing occurs whenever the rated conditions are exceeded. From engineering and economical standpoint, the most favourableconditions for a power supply is attained when the power factor is close to unity .Thus in order to attain increased voltage levels on the load and reduced electric utility bills, a temperature monitoring and power factor correction circuit is also included.
