Abstract
Electrical energy is an important component in an industry, that is needed by electrical equipment / machines that exist in the industry. Currently, the majority of electrical energy is produced from fossils. Therefore, efficiency application of electricity loads in industries need to be logged and analyzed. To make electricity load efficiency possible, it can be done by monitoring and logging real-time electricity loads in the industry. So that, the electrical power consumed can be analyzed. In this paper, a 3-phase electricity monitoring system is builded for Low Voltage Power Distribution (LVDP) that can be monitored anytime and anywhere via internet for the needs of electricity quality analysis. Monitoring parameters are voltage, current, real power, apparent power, power factor, IHD voltage and current, and voltage and current THD for each phase. That variables send to database and display on the web. Error reading of voltage sensor is found on average error 0.00254% compared to multimeter. For current sensor, the average error is 0.0074%. On the user interface, all functions are running well, so that, it can be utilized for the needs of electrical analysis, which means the power consumed and the malconsumed can be known.
