Abstract

Electric current distribution on water is a phenomena that occur when any electric current source present on water and distribute the current in all possible way. As an example, the lightning strike on water, leaking under water cable and wet polluted insulator. The current that distribute on water could not only caused a lot danger to the life, but also to the equipment and material. Tidal wave generator safety are the main concern if the lightning strike at the sea. However, current discharge on water also could give benefit on water treatment.Current distribution on water depend on the water conductivity itself, as the higher salt concentration on water, the higher magnitude current could be draw. The experiment that has been set to observed current distribution on water consist of impulse voltage generator and water tank equipped with iron electrode. The tested water are tap water and saline solutions. The imitation of lightning are created using the impulse generator and the discharge are pointed at the water. The current measured by using Rogowski coil. The result show that current distribute by sprouting into a water , and the underwater current distribution is more higher than surface distribution. The dissolve salt in the liquid could also draw a higher magnitude of current. The measurement and observation could be improved by implementing high speed camera for observation purpose, and also the addition of Rogowski coil quantity could give more consistent and higher accuracy reading.
