Automated Maintenance of Protective Relays

Abstract

The paper presents a Power system that relies on protective relays to monitor critical electrical quantities and initiate emergency shutdowns on the detection of out-of-limit conditions. Instrument transformers, such as potential transformers (PT) and current transformers (CT), reduce the power system currents and voltages to levels usable by protective relays and other control and metering devices. We develop a framework for automated testing of protection devices i.e protective relays, current transformers (CT), and potential transformers (PT) in real-time using multiple sensor inputs. Also using the ANN Algorithm to train the ANN model to minimize the relays tripping time . Using the inputs from different sensors that are connected to the relays and associated monitoring equipment. This offline time results in some financial losses as well. We want to automate the tasks mentioned to make our grid more reliable and to increase operational efficiency this way, you can plan maintenance in advance, reduce Human work, eliminate unplanned downtime, and maximize equipment lifetime.
