Priority Based Automatic Electrical Load Control for the Prevention of Electrical Overload in Household Installations

Electrical energy plays a role in supporting human activities, one of which is in the household sector where electricity demand is relatively high. Another problem that occurs in households is the MCB trip due to overload. An electrical monitoring and automation system is needed for household utilities to monitor the use of electrical energy and prevent MCB trips. The monitoring system utilizes the PZEM004T module and is integrated with IoT so that energy consumption monitoring is carried out in real time. Electricity costs are also calculated. Load trip automation is carried out with priority based on current control to prevent overload. The lowest priority load will trips to prevent MCB trips and limit energy consumption. The measurement of the amount of electricity by PZEM004T displayed on the IoT platform has a current error of 4.4%, respectively. In addition, data transmission traffic is considered so that the data displayed is in accordance with the actual situation with delay, jitter, packet loss and throughput obtained 103.4 ms, 103.4 ms, 0% and 61.06 kbps, respectively. The load trip is precise in deciding the lowest priority load to the higher priority load until a current is less than equal to 5 A. Energy consumption after using the system to limitate the current use is 1,80 kWh which is reduced to 0.15 kWh of energy consumption without using the system.
