DESIGN AND IMPLEMENTATION OF AUTOMATIC TRANSFORMER OVERLOAD PROTECTION SYSTEM

Load sharing provides sufficient protection to distribution transformer under overloaded conditions. Due to overload on transformer, the efficiency drops and windings get overheated and may burn. By sharing a load current on transformer for each phase the transformer was protected. Therefore, the objective of this study was to protect transformers from overloaded conditions by sharing the load. Because of the differences in our college level studies and industry level requirements, we are allotted a project to get knowledge about the on goings at industries. I did the mini project that covered up a practical knowledge of what I have studied so far in books. I did experience an exposure to various electronics devices and equipment’s which I would not have able to get easily anywhere else. In electric power distribution, an automatic overload protection System Is a circuit breaker equipped with a mechanism that can automatically close the breaker after it has been opened due to a fault. Automatic overload protection systems are used in coordinated protection schemes for overhead line power distribution circuits.
