Electrical status display for maritime switching equipment e.g. for containers storage on board ship, has electrical state of each phase of system queried at measurement- and test-points ready for optical display

摘要

An electrical status display having a multi-phase electrical layout of the containers socket-outlets, consisting of measurement- and test-points, input voltage power switch and output voltage, the electrical state of each of the phases is queried at the measurement- and test-points, and processed and can be optically or acoustically displayed.
