The type of electric motor commonly used in industrial activities is the induction motor. The use of induction motors reaches 95% as a prime mover and utilizes up to 40-50% of all electrical energy produced by power plants. Although induction motors are very reliable with a low failure rate and only require basic maintenance, they can sometimes break down and fail. . Detecting problems early an…
This research analyzes the calculation of capacitor bank values to repair the voltage drop that occurs on the TG5-6 3.3kV bus at PT Indah Kiat Pulp and Paper of 0.06pu. The voltage drop standard that is set is 0.05 pu or 5% (ANSI C84.1-1995). The analysis is carried out based on power flow by modifying the bus load type (PQ) to become the controller bus voltage (PV). Assuming that the bus load …
This research aims to minimize the frequency and duration of outages at points unaffected by disturbances through maneuvers. It also seeks to determine the reliability level of the distribution network in the Munchen feeder before and after the maneuvers. The study involves analyzing the maneuvers in the Munchen feeder to assess the reliability of the distribution network, including both SAIFI …
Induction motors are the most common type of electric motor used in the industrial sector throughout the world. The use of induction motors reaches 95% as the main mover and utilizes up to 40-50% of all electrical energy produced by power plants. However, although induction motors are very reliable with a low failure rate and require only basic maintenance, they can sometimes break down and fai…
The distribution substation is a distribution system whose function is to distribute the network to consumers, both medium voltage consumers and low voltage consumers. In distribution there is always a problem, namely load balance. As a result of loose loads in a distribution system, there is the emergence of a neutral current, the current flowing in the neutral transformer will cause power los…
The imbalance of loads in the distribution transformer always arises due to uneven electricity usage. The consequence of this load imbalance is the flow of current in the neutral conductor of the transformer, leading to losses. Other losses in the transformer include power losses, core losses, and copper losses. Problem analysis using a mathematical model involves calculating the percentage of …
In the current era of globalization we cannot be separated from technological developments. Currently, convenience and efficiency of time and energy are the main considerations for humans in carrying out activities. The results of this technological development include the application of Arduino Uno to make automatic plant watering devices, especially for strawberry plants. Chili plant care gen…
Counting the number of visitors entering the museum area is generally still done manually by existing officers. This does not rule out the possibility of frequent errors by officers due to staff being divided in concentration or lack of accuracy which results in damage to historical relics in the museum. Due to this problem, a tool is needed that functions to count the number of visitors. This …
Herbal tea is a drink made from different types of herbs, such as the leaves, seeds, or roots of plants. Herbal tea can have various health benefits, depending on the type of plant used. The objectives to be achieved in this study were to make herbal tea from arabian bidara leaves by knowing the effect of different drying times on testing water content, yield and ash content, and comparing the …
Electrical Engineering is one of the majors at Riau University. Most academic activities in the Department of Electrical Engineering are still carried out manually, such as determining the schedule for Practical Work (KP) seminars, Proposal Seminars and Thesis Sessions. In the Department of Electrical Engineering, the problem faced is that scheduling similarities and delays often occur. Schedul…
Izdiihar Laptop Store, a small business in the field of laptop repair and sales, has problems managing transactions and customer data manually. Recording transaction data that is scattered in various manual records causes difficulty in the data search process. Another problem was the absence of an overall laptop repair transaction report.
