Abstract

Globalization era has a negative impact on the environment, one of which is affected by temperature. The condition of a hot room can cause an uncomfortable feeling to move in the room. The best room temperature for human comfort is 29°.ECOSYSTEM is an air conditioner that uses an indirect evaporative cooling system with control using Arduino uno and an application. This tool is made to cool the air in the room with the control of a cellphone. This research can be proven to be successful because the program code with the tool runs well. From the experiment it is also proven that when the speed increases, the current, watts, and RPM increase linearly.With this ECOSYSTEM tool, it is able to cool the room compared to a fan. Although the power generated is greater. Because the components used are different from conventional fans.

Abstract

Electricity is a collection of components or electrical devices such as generators, transformers, transmission lines, distribution lines, and loads, which are connected and form a system. Maintenance is one of the most important things that must be considered in the operation of the electrical system. Voltage transformer is a device that transforms a higher system voltage to a lower system voltage for indicator equipment, measuring instruments, and relays. In this research, quantitatively, this is done by testing from the box panel on the voltage transformer and each coil has ameasuring limit, recording the test results is carried out at 60 seconds and there are 2 places, namely busbar 1 and busbar 2 and 6 measurements of insulation resistance on the transformer. voltage. This test is not on Phase R and Phase T because the equipment is being transferred to another substation. The results of the voltage insulation resistance test under normal and good conditions are above the minimum limit of insulation resistance and the voltage transformer is fully operational.
