Depending on the level of discharge, the modification made on the standard relay and connecting cable, is validated and subsequently deployed in an underwater application. To control high-voltage or high-power circuits with an Arduino, you have to isolate them from the Arduino with a relay. A possible way to achieve this is by suitably modifying the existing low‐cost devices to meet the requirements of underwater application. It has the advantage of consuming little current, around 150 µA. Later, the chosen samples are emulated at underwater conditions and subjected to conventional and non‐conventional partial discharge test methods.
