Design of Fuse Cut Out (FCO) Detection Tools Break-Up on Internet of Things-Based Distribution Substations to Speed up Response Time of Disorders

The distribution system is the most important system in the electric power system. In maintaining reliability and providing the best service to its customers, Indonesian electrical company (PT. PLN) prepares an electricity service officer who is ready 24 hours to handle disturbances that occur in the distribution system, one of which is disturbances in the distribution substation such as the breakdown of fuse link on fuse cut out (FCO) where the disorder is often known for a long time, which affects the response time (response time) of the officer in knowing the disturbance so that it has an impact on the voltage drop on the customer. In accordance with Indonesian national standard of electricity number 1 of 1995 which regulates the service voltage variation is determined at a minimum of 10% against nominal voltage, with this basis then if the voltage reads more than 10% with the parameter reading on the distribution substation every approximately twenty seconds, then the tool will send Indications of Fuse Link Breaking on FCO along with the size of the fuse link, current, voltage and address of the distribution substation to officers via message on the Telegram application in real time.
