Abstract
A leakage detection system includes a sensing unit that contacts a leakage liquid, a resistance measuring unit configured to measure an electrical resistance of the sensing unit by applying a direct current to the sensing unit, and a determination unit configured to determine whether the leakage liquid is a dangerous solution or a safe solution based on a first graph showing a change over time of the electrical resistance measured by the resistance measuring unit, wherein the dangerous solution is an acidic solution or an alkaline solution and the safety solution is water.
