This research aiming for build and design a single phase constant time overcurrent relay (COTR) system based on Arduino Uno. COTR is a device protection used for protect equipment electricity from overcurrent. This system designed for working on network single phase electricity with using Arduino Uno as component main controller. Principle COTR’s work is measure flowing current through load and decide connection electricity if current exceed the value that has been set in constant time. Design system covering making current sensor circuit, circuit conditioner signals, and control programs on the Arduino Uno. System this expected can become alternative cheap, reliable and reliable overcurrent protection applied to various type burden single phase electricity.
