Automatic Load Sharing of Distribution Transformer for Over Load Protection

Nivesh Kumar K.


Abstract: The main aim of this paper is to indicate the methods we are using to reduce the faults in the transformer and we are also able to protect the transformer. A transformer is a constant device that transfers electrical power from one circuit to another with the desired change in voltage and current at a constant frequency. But when it overloads the condition causes abnormality, which can cause serious problems in the future. To avoid such a situation when there is a high load on the main transformer, we use other standby transformers that provide loads, which are switched on automatically by the Arduino. This will lead to efficient loading of both transformers. When the load is normal, both transformers can be switched to alternate loads. This will avoid the thermal loads of the transformer. Also, this arrangement will provide a proper maintenance facility for both the transformers. The transformer is the most expensive and bulky piece of equipment in an electrical system. It operates 24 hours a day and feeds the load. The situation can sometimes occur when the load of the transformer suddenly increases beyond its rated capacity. When this condition occurs, the transformer will be overloaded, overheating and damaging the insulation of the transformer, resulting in clogging. The best solution to avoid overloads is to run the number of transformers in parallel. This is as same as the parallel operation performed by the transformers, where the number of transformers shares the system load. In the recommended approach, the load of the first transformer will share loads of the second transformer when it rises above its rated capacity. The main objective of this paper is to provide an uninterrupted power supply to the consumers and also to protect the transformer from overload condition. By implementing this scheme the transformer can avoid supply interruption due to high load or high heat.
