Wireless Sensor Network Based Atmega16 Microcontroller as Temperature and Current Monitoring System on Distribution Network Transformator

Distribution transformers is one of the main component in electrical distribution system to customer. This transformers is used to change the input of the transformers from 20 KV to 220 Volt. Distribution transformers often has disruption, and if it is not fixed soon, it will damage transformers and fire it. One of the parameter that indicate disruption in transformers is enhancement of current and temperature of transformers significantly. A monitoring system is needed to avoid damaging the transformers which uses current and temperature as a parameter. A monitorng system can be built by wireless sensor network as the main system which every node can handle more than one sensors that can be controlled from far away. This research aims: (1) to get simulation system of wireless sensor network as a monitoring system based on Atmega 16 microcontrollers, (2) to analyze wireless sensor network as a monitoring system of distribution transformers. Method that is used in this research is Reasearch and Development. Which starts from making the simulator and after that make simulation with the hardware that has been made, and analyze data from simulation. Result of this study showed that: (1) the simualator that has been made is work fine and getting closer with the system in a real world, (2) based on regression analysis, the regresion line is significant to predict Y value (temperature) based on X value (current), which has relation values is 96.2%, with bias and relative error for current values is -0.038 and 2.52%, bias and relative error for temperature values is 1.008 and 1,21%.
