Abstract

The Unbalanced load with a significant difference in the electricity distribution system causes the emergence of a neutral current, causing losses due to the flow of neutral current to the ground, overheating in one phase, and resulting in a decrease in quality and damage to the distribution transformer if it lasts for an extended period of time.  The goal of this research is to design and build a monitoring prototype for measuring current, voltage, and percentage of unbalance on a distribution transformer prototype, with the goal of providing measurement data from the prototype via the internet. The Arduino Uno serves as a data processor from current and voltage sensors, and the ESP8266-01 serves as a wifi module, sending current measurement data for each phase, line to neutral voltage, and the percentage of load imbalance to the Thingspeak Web Server in the form of seven graphic displays that PC/ smartphone users can access online. The overall performance of this tool can work well by improving the measurement accuracy of the current sensor SCT 013-000 using a tuning approach, so that the resulting error meets the standard error of the measuring instrument.

Abstract

Electrical Machinery Laboratory, University of Medan Area is one of the laboratories based on energy conversion, and it requires a large source of electrical energy with a variable voltage (voltage can be set from 0.) The excitation system is a DC power supply system as a reinforcement to an electric generator or generator. as a magnetic field generator, so that a generator can produce electrical energy with a large generator output voltage depending on the magnitude of the excitation current. The excitation voltage required to meet the demand is 82 Volt DC. From the results of the test data obtained by 98.1 Volt DC, this is already sufficient to be able to regulate the variable generator excitation voltage. So that the planning of this tool can make it easier to regulate the excitation of the generator from wherever it is, both from a short distance and long distance without using a cable (wireless) by using the Remote Control.

Abstract

Lighting systems that are not up to standard will have an impact on eye fatigue so that the work results of the staff are not optimal. This problem can be solved by designing a lighting system according to the standards that have been determined through the results of previous studies. The 1st floor of the Faculty Engineering, Universitas Medan Area building requires lighting improvements to provide comfort to all staff and lecturers. This research was conducted by measuring the value of light intensity in each room and improving the lighting system which was analyzed through the shape of the room, the color of the walls, and the position of the lights. The results of the study provide additional light points and the position of the lamp according to the utilization.
