Abstract

Renewable energy technique is the process of converting available ambient energy into usable electrical energy through the use of a particular material or transduction mechanism. Nowadays, the evolution of new technology which involving renewable energy technique and smart grid system has a huge potential in the energy market. In line with the current technology interest in the smart grid technology, power transformer health condition becomes one of the main issue need to be considered. The way to monitor health condition of the power transformer has started to evolve from typical monitoring technique to a new development of using energy harvesting technology to activate sensors network for the monitoring purpose. For this project, Thermoelectric Power Generator (TEG) is used to convert the heat energy get from the power transformer into small electrical energy in order to power up electronic devices that will triggering up the monitoring system. TEG only produces small electrical energy, so the boost converter is needed in order to increase the electrical energy from the TEG and get its maximum power point tracking (MPTT). The boost converter is a type of DC-to-DC converter which has a greater output than the input voltage. So, the result of this project will show us the small electrical energy, converted from the heat energy , range between 20 mV to 1.5V that is get from the TEG will be raised up until at least 5V using a boost converter. 5V is the minimum volts to trigger up the PIC circuit or any others small electronic appliance that has low power consumption.
