This is a very innovative project in electrical stream that controls the grid transformer. If load current increases to a certain pre-defined level, a grid changeover relay shift the phase from a to b. Thus, a certain load devices automatically connnected to the other phase that inturns protect the control panel & grid tripping. This is a complete, assembled working project / model (duly tested) at our work shop. This is a handmade project on a general purpose PCB and uses Electronics / Electrical components as per requirement of a particular model. A rough report & study material related to project will be mailed to student on request.
