This project proposes an innovative design to develop a system based on microcontroller that is used for monitoring power of a distribution transformer in a substation and to protect the system from the rise in above mentioned parameter. Protection to the distribution transformer from the main station is done with the aid of the ZIGBEE Communication. Moreover the system displays the same on a LCD at the main station that will lead to avoid the damage in substation. The design generally consists of two units, one in the substation unit, called as transmitter unit, and another in the Main station called as controlling and receiver unit. The transmitter in the substation is where the power is monitored continuously by PIC microcontroller. A ZIGBEE is used for transmitting the signals that are obtained. The controlling unit in the main station receives the transmitted signals by means of ZIGBEE receiver and displays in LCD and LED and reacts in accordance to the received signal.
