Desain Alat Deteksi Anomali Arus Bocor dengan Gabungan Sensor CT dan Logika Fuzzy

Abstract

Leakage current in electrical systems is often a source of equipment malfunctions, energy waste, and safety hazards such as electric shocks and fires. Conventional protection systems typically rely on fixed threshold limits, making them less adaptive to changes in load and environmental conditions, which can reduce detection effectiveness. This study aims to design a leakage current anomaly detection device that integrates a Current Transformer (CT) sensor with fuzzy logic. The CT sensor functions to detect differences in current between the phase and neutral conductors, while fuzzy logic is employed to analyze the anomaly level based on the magnitude of leakage current and current stability. The design results demonstrate that the system can classify electrical installation conditions into three categories: normal, alert, and danger, using a more flexible approach compared to conventional threshold methods. The implementation of this device is expected to enhance the reliability, efficiency, and safety of electrical systems, while providing a more adaptive response to load variations and potential disturbances.
