Perancangan Prototipe Sistem Pemantauan Kelistrikan pada Industri Konveksi Berbasis Komunikasi Telemetri 433MHz

Abstract

Convection is a business in the field of fashion products that are made en masse and in large quantities for every day. The use of many electric machines and operated simultaneously in the convection industry can increase the amount of electric current flowing in convection industrial building installations and some electrical disturbances such as electrical disturbances, namely short circuits and more loads. Based on the results of system performance analysis the incre ase in the percentage of data loss is directly proportional to the increase in the transmission distance of sending data, data loss at a distance of 40 and 80 meters is 0%, data loss at a distance of 120 meters is 5%, data loss at a distance of 160 meters is 10% and data loss at a distance of 200 meters is 20%. The average percentage of voltage measurement error on the ZMPT101B sensor is about 0.47%, the average percentage of current measurement error on the ACS712 sensor is about 0.246%. an short circuit. peningkatan jarak transmisi pengiriman data, data loss pada jarak 40 dan 80 meter yaitu 0%, data loss pada jarak 120 meter yaitu 5%, data loss pada jarak 160 meter yaitu 10% dan data loss pada jarak 200 meter yaitu 20%. Rata rata persentase error pengukuran tegangan pada sensor ZMPT101B sekitar 0,47%, rata rata persentase error pengukuran arus pada sensor ACS712 sekitar 0,246%. Short circuit analysis occurs at a current of 2,171.11 amperes assuming a synthesance of 0.1 ohms and the use of electrical power in the 5th condition of 3,289.47 Watts will produce an electric current of 15.17, then in this condition the relay will cut off the flow of electricity when the current exceeds 15 amperes at excessive load and short circuit.
