engineering SISTEM PROTEKSI MAIN PANEL DISTRIBUTION DENGAN OVER VOLTAGE RELAY DAN OVER CURRENT RELAY
AbstractElectrical energy, have three main systems. The three system are generation, transmission and distribution. Distribution is the most important component, because distribution is directly related to consumers. If there is a disturbance in the electrical system, it can cause damage to electrical equipment and also affect community activities.so its necessary to have the main safety in the form of protection to protect the current and the voltage.in this study, the design of a current and voltage protection device in the form of an arduino based three phase panel.to meet these needs, the measurement uses current sensor and voltage sensor PZEM-004T.this design is equipped with an SD card module that functions to retrieve data and excess current. purpose of making a main panel distribution protection system with over voltage relay dan over current relay can secure the distribution network using load from overvoltage and over current. The methodology used in the design of this final project is literature study, mechanical and electronic design and report generation, the conclusion that over current relays and over voltage relays protect each line from electric current so as to protect the load
