Autoplay when autoplay is enabled, a suggested video will automatically play next. Pdf project proposal form of automatic transformer distribution and load sharing system. Further the project can be enhanced by using thyristor control switches instead of relay control to avoid contact pitting often encountered by switching of capacitors due to high in rush current. In this work, the slave transformers share the load of master transformer in the case of over load and over temperature conditions. Automatic load sharing and control system using a microcontroller. In this work we are used a relay and comparator ic. Rectifier, filter and regulating circuit power circuits. When the load exceeds the reference value, the slave transformer will automatically be connected in parallel with first transformer and share the extra load. The aim of the project is to protect the transformer under overload condition by load sharing. A sensor circuit containing microcontroller, current transformer etc. Distribution and load sharing of transformer automatically by. Power transformer protection using microcontrollerbased relay.
Doc of automatic load sharing of transformers microcontroller. Automatic load sharing of transformers transformer power. This whole process is totally automatic by using the microcontroller. Automatic load sharing of transformer using microcontroller. Distribution and load sharing of transformer automatically. The transformer is a static device, which converts power from one level to another level. Load sharing provides sufficient protection to distribution transformer. So in this paper an automatic power factor correction circuit is also incorporated with the load sharing module. Load sharing module distribution transformer is a critical equipment in power system. Automatic load sharing of transformers using microcontroller akhil krishnan v 1, arun p s1, d yathishan1, jomice thomas 1, d 2k narayanan u. Automatic transformer distribution and load sharing using. Therefore, a number of transformers work efficiently under overload condition and the damage can be prevented. Once load has been increased on first transformer above its rated capacity then the stand by transformer second will share the load automatically. The concept of automatic load sharing of transformer or overload protection of transformer is done by various means like by using microprocessors, by using gsm technology, and by using relays.
