Abstract

Kilo Watt Hour Meter or kWh meter is a tool for calculating the amount of electrical energy used by electricity consumers, both residential and industrial customers. The electrical energy used is then converted into the electricity price that must be paid each month. Currently, most kWh meters in circulation are smart kWh, which use electricity tokens as transaction calculations. Customers must fill in 20 token numbers via the kWh meter keypad to fill in electricity tokens. Filling in this 20-digit token is not easy, this is because usually, this type of kWh is placed in a higher place to avoid the reach of children. This placement sometimes causes problems with replenishing the token, and users must start over from the beginning. This research aims to create a tool to fill in electricity token numbers that can be controlled using an Android application, making it easier for users to fill in electricity tokens remotely via smartphone. Apart from that, this system has feedback in the form of notifications that display numbers that failed to be filled in on the kWh meter. Test results show that this system can function well from 10 meters without obstructions and 9 meters without obstructions.

Abstract

Torque ripple analysis and calculation methods in an axial-type Magnetic Gear (MG) design with four rectangular NdFeB magnetic layers have been reviewed and discussed. Smooth and steadily transmitted torque is an essential characteristic of a magnetic gear. Reducing possible mechanical vibration, position inaccuracy, and acoustic noise is necessary. Therefore, this study aims to design a new engineering method appropriate for calculating the torque ripple of the MG transmission by testing its mechanical and electrical properties. Two simultaneous torque tests compare the MG brakes from zero to full load. In addition, the transmission torque of the axial MG is measured and calculated using technical methods. The results showed that differences in dynamic torque occurred in the MG at various air gap distances.

Abstract

In the digitalization era, protecting electrical equipment in low voltage systems of 380/220 V is crucial to ensure operational reliability and safety. This study explores the effectiveness of a protection and monitoring system based on the Internet of Things (IoT), integrated with the Telegram application, for detecting disturbances such as overvoltage and overcurrent. The methodology employed is a quantitative experimental design, involving system testing with smart sensors and relays. The test results demonstrate that the system successfully provides real-time notifications to users within an average time of 2 seconds after a disturbance is detected. With this system, users can promptly be informed about voltage and current conditions that may potentially damage equipment, thereby allowing for swift actions to prevent damage. In addition to enhancing responsiveness, this system also facilitates remote management of electrical systems. The findings of this research emphasize the importance of implementing modern technology in electrical system protection, which can reduce the risk of damage and improve energy management efficiency.
