Abstract
A method and an arrangement to detect and protect an electrical device against short-circuiting due to a presence of a conductive subject are provided. The arrangement may include a first and second probe, the first probe connecting to an electrical ground and the second probe connecting to a detecting device, the detecting device being configured to detect a short-circuit between the first and second probes, and output a signal to interrupt power supply from a power source to electrical components of the electrical device.
