Design of an Over Current Relay (OCR) System on a Distribution Network Using a Raspberry Pi
Journal Geuthee of Engineering and Energy, 2023 Disturbances in the electrical installation system will be detrimental to electricity users because it can cause power outages. Therefore we need a protection system that can overcome disturbances such as the use of Over Current Relay (OCR). With OCR can
