This research discuss about sceme and making of digital KWh meter by using current transfomator based on MC AT 89S51 which use the fundamental components such as current transformator, full wave rectifier and voltage devider, ADC, Microcontroller, and LCD as visual indicator. This digital KWh meter is a vital component in the daily customers electric usage. By this tool, the expense of electrisc usage can be monitored by the customers. This research is created to help users for monitoring the usage of cost and energy. The first step creating this system is detecting the change of current by current transformator. Then, the current will be rectified by full wave rectifier. The voltage is degraded by voltage divider, then analog voltage will be changed in to digital by ADC, then it will be processed by MC AT 89S51, and the last step is presenting them in LCD. From This System sceme, we get a conclusion that this system can measure the expense between 10 – 100 watt with mean error of the amount KWh rotation equal to 0.095 second. The rotation data of KWh and Rupiah amount can be presented to data base at PC after remote control ask for data of KWh and transfer it to PC.
