S. VASAVI, A. RANJITHA, K. KISHORE, N. PAVITHRA, S. V. LAKSHMI KUMARI Result is obtained when code is dumped into the Node VII. FUTURE SCOPE MCU, all the sensors are connected and senses the The project portrays about how to utilize control supply parameters and gives the result to Node MCU, the ADC astutely under pinnacle loads. The project naturally converts the analog signals into digital signals and the values interfaces and disengages the transformer consequently are monitored on the serial monitor in PC using Arduino shielding transformer from over-burden. Detecting unit, i.e., IDE as shown in Fig.6. Here three 100 wt bulbs are Current transformer assumes an imperative part by detecting connected to three phases and 1000 wt bulb is connected to the current through the heap and sending input flag to the one of the phases , when the 100 wt bulbs are active then the microcontroller. Microcontroller is programmed to the point load is in normal state and cooling fan starts automatically as that when the heap surpasses a specific ebb and flow restrict shown in Fig.7. If the 1000 wt bulb is active along with three it will soon produce a control flag that would be intensified loads then the transformer is said to be over loaded and the by the driver unit and at last control flag is bolstered to the servo motor trips to share the load with idle transformer, hand-off. The exchanging procedure happens in the Relay then the transformer which is connected to load and idle which naturally associates the transformer in parallel in transformer are connected parallelly then the load sharing is agreement to the heap detected by the CT. The future extent done automatically. of our project is especially in Substation. In substations especially amid the pinnacle hours there is a requirement for the task of extra transformer to supply the extra load prerequisite. Our project consequently interfaces the transformer under basic burdens. Therefore there is no compelling reason to work the two transformers under typical burdens, especially amid off pinnacle hours. In this way control is imparted wisely to the transformers in parallel.
