Abstract

Abstract An overcurrent relay is an important device in protection systems to protect electrical equipment from damage caused by excessive overcurrent. The objective of this study is to design and implement an overcurrent relay system that can detect and mitigate overcurrent using the inverse time protection principle, developed using the popular and accessible Arduino platform. An overcurrent relay (OCR) is an electrical protection device that operates based on overcurrent detection. There are two main characteristics, namely inverse time and constant time.Inverse Time Relay cuts off overcurrent with an operating time that increases as the current increases, while Constant Time Relay has a fixed operating time. This research discusses the working principles, differences in characteristics, and applications of both types of relays to improve the effectiveness of protection in electrical power systems.

Abstract

A striking disparity, when connected to big cities that are already supported by fast internet access. However, there are still areas where access to electricity is still hampered. It is true that building a PLN network for these areas will give rise to many challenges. However, there is actually a more efficient solution to this, namely the Solar Power Plant (PLTS) either communally or individually or SHS (Solar Home System). In the utilization of Communal PLTS, there are two types of systems that can be applied, namely the On-Grid and Off-Grid PLTS systems. The term On-Grid refers to a solar panel system that is connected to the PLN electricity network. Panels that use this system will only generate electricity when there is still electricity in the grid. This is because the electricity generated by it cannot be stored as backup energy. While the use of SHS is prioritized for communities that are far apart from each other. In Kutai Kartanegara Regency, there are still many isolated rural areas. One of the areas that is difficult to reach by the PLN electricity network is Tunjungan Village, Muara Kaman District. In 2021, Tunjungan Induk Village has installed an Off-Grid Communal PLTS, while the Tunjungan Seberang area is still experiencing problems in reaching electricity. To overcome the problems faced by areas that are difficult to reach by the PLN electricity network, the Community Service Team of the Electrical Engineering Department of the Samarinda State Polytechnic carried out community service in Tunjungan Seberang Village, Tunjungan by installing a Powerwall as an Independent Electricity Source for the needs of the Tunjungan Seberang house of worship, Tunjungan Village, Kutai Kartanegara Regency.

Abstract

This system is designed to detect overcurrent faults, then disconnect them from the circuit. In inverse time overcurrent relay, the relay trip time will depend on the magnitude of the fault current. The greater the fault current, the shorter the relay trip time will be. Meanwhile, in definite time overcurrent relay, the relay trip time will work according to the specified time. This system consists of Arduino Uno, PZEM-004T, and relay module. PZEM-004T acts as a current sensor that can measure the current value flowing in the load. Arduino Uno is used as a microcontroller that can process data that has been measured through PZEM-004T. Then, if the current flowing in the load has exceeded the specified value, the Arduino Uno will activate the relay that can disconnect the current flowing in the load. The system was tested using an induction motor and variable resistor. The test results show that this system works effectively and efficiently, and can protect the load from damage due to overcurrent faults
