What is one of the main concerns regarding moisture in electrical systems?

One of the main concerns regarding moisture in electrical systems is that it can cause corrosion and short circuits. When moisture enters an electrical environment, such as circuit boards or connectors, it can lead to the formation of conductive paths between components that are not intended to be electrically connected. This can result in unintended current flow, leading to short circuits, which can potentially damage components, disrupt operations, or even create safety hazards. Additionally, moisture can promote corrosion on metal contacts and connections, degrading their performance over time and leading to failure. Therefore, controlling moisture levels is crucial in maintaining the reliability and safety of electrical systems.
