Abstract— University of Lampung (Unila) as an academic institution should provide the internet service for thousands of users, monitoring the condition of electricity (Voltage, Current, Power factor, Power, and Energy consumption measurement) at ICT center building has an important role, as a part of maintenance lifecycle to make sure the internet services running well, system monitoring implemented in order to know the quality of electricity supply in the system, identifying disruption events, and to calculate the amount of electrical energy usage periodically. In this research we made an application to monitor the electrical quantities in real time, and shown the statistic reports through web interface. This research was conducted on the 3-Phase electricity network at ICT center building Unila. Monitoring of voltage was done by using a step-down transformator as voltage sensor, and Current Transformer SCT-013 100A as current sensor. Energy, Power, and Power Factor value was obtained by some of scientific calculation. Python programming language was used to develop the application, mainly for data acquisition and calculation that run on BCM2835 Embedded Single Board Computer. The result of this research shown that energy consumption for each Phase was not in balance, 1st and 2nd Phase mostly high load during working hours only, while 3rd Phase energy consumption relatively stable at all time, this happen because 3rd Phase connected to Data Center which consist of several server and network equipment that always online for 24 hours. Keywords— 3-Phase electrical networks, embedded system, voltage sensors, current transformer SCT-013 100A, energy consumption, BCM2835 embedded single board computer.
