Abstract

In load monitoring testing using Simulink on DC loads, an error was obtained between the measurement results and thevarious theories. The smallest error obtained is equal to 0.088737464% in the 15 Ohm shear resistance test, while thebiggest error is -22.68571337% is found in the monitoring of 30 Ohm sliding resistance load. In the AC load monitoringtest using Simulink, an error was obtained between the results of Simulink measurements with conventionalmeasurements using an ampere meter and an analog voltmeter. The smallest current measurement error is 3.433806453%on the measurement of the lamp load current and the largest is 17.30705898% on the measurement of the fan loadcurrent. While the smallest voltage measurement error is 0.164816128% on the measurement of the iron load voltage andthe largest is 0.928443504% on the fan load measurement. The measurement values of both current and voltage sensorsshow varying measurements, this is due to the current sensor in dc load, the current obtained tends to be more stable, butfor loads with small currents the sensitivity level of the readings decreases. Whereas in the reverse AC load, the accuracyof the current sensor is not stable because the reading source is alternating current, but for large loads, the sensitivitylevel of the current readings improves.
