Abstract
One of the shortcomings of the electrical system in the Electrical Building is that there is no data (display) on the use of electrical loads, especially the Interface Design Lab and Programming Lab in real time. Therefore, a monitoring tool for the use of electrical loads was designed so that the peak load and the lowest load of the use of electrical loads can be known. This tool is also equipped with an LCD to display measurement data such as voltage, current, cos phi and power. This tool is also equipped with an RTC and SD card that work to send measured data every hour and will be stored on the SD card. The measurement data that has been stored on the SD card will be processed with MATLAB using PSD to see the form of density of electrical load usage. The PSD method is used to identify patterns and characteristics of electrical load usage from electrical current measurement data taken every hour for 14 days. Electrical current data is analyzed using Fast Fourier Transform (FFT) to convert data from the time domain to the frequency domain. The results of the analysis show that there is a dominant frequency component in the low frequency range (0-1 Hz), which indicates a recurring daily electricity usage pattern. The peak electrical load was found to occur during active working hours, reflecting the intensive use of electrical equipment during that period. By understanding electricity load usage patterns, energy saving strategies can be planned more effectively, such as scheduling the use of heavy electrical equipment at non-peak times.
