Abstract
Electric current measurements in electric power systems are important aspects that need to be monitored for protection. Therefore, this study designed, implemented, and tested a digital current measuring and recording prototype instrument. The current signals of the loads were sensed by the split-core transformers, which entered the signal conditioning, through the Arduino Mega 2560 microcontroller, and emitted output through a PC monitor, SD card data logger, and LCD. Furthermore, the device was tested with the results compared to the computation and clamp ammeter readings, as the reference values. The testing loads are 1500 W and 500 W for single-phase and per-phase of three-phase systems respectively, due to limitation of the loads. Both single and three-phase systems exhibited an increase and decrease in the absolute and relative deviations, respectively, due to an increase in load.
However, the values in both systems were not the same. For the single-phase, the average absolute and relative deviation slopes were 0.156548 A/kW and -0.0020772 %/kW, respectively. On the other hand, for the three-phase system, they were 0.12372 A/kW and -0.04176 %/kW, respectively. The relative deviations to the computation results were under 6%, and decreased to 3%, while the relative deviations to the reference instrument readings were under 3%, decreased to 1%, as the load increased. Therefore, the accuracy is within between 1% and 3% of that yielded by instruments generally used for measurements.
