Automatic Transformer Distribution And Load Sharing System 6l2k6v

Automatic Transformer distribution and load sharing system Abstract : Power travels from the power plant to house through an amazing system called the power distribution grid. for the power to be use full in a home or business, it comes off the transmission grid and is stepped-down to the distribution grid. this may happen in several phases. The place where the conversion from “transmission” to “distribution” occurs is in a power substation. It has transformers that step transmission voltages down to distribution voltages. It has a “bus” that can split the distribution power off in multiple directions. It often has a circuit breakers and switches so that the substation can be disconnected from the transmission grid or separate distribution line can be disconnected from the substation when necessary. In this project a slave transformer in this case of shares load of master transformer over load and over temperature. A sensor circuit is designed to log the data from the master transformer and if it is found to be in over load condition immediately the slave transformer will be connected in parallel to the master transformer and load is shared. LM324 operational amplifier is used to compare the load of the transformer with a standard load capacity. An n-p-n transistor is used to drive the relay. This project regulated 5V, 750ma power supply .7805 three terminal voltage regulation. Bridge type full rectifier is used to rectify the ac output of secondary 230/12V step down transformer.

Advantages: 1. Automatic Load Sharing by Transformers 2. No manual error fit and forget system 3. Highly sensitive low cost and reliable circuit
