A DC earth fault in a rectifier cabinet occurs when a live DC conductor touches a grounded metal part, allowing current to flow to earth. This is a dangerous situation that can cause overheating, equipment damage, and equipment failure. NASN POWER B series rectifier cabinets include microprocessor-based earth fault detection systems that continuously measure insulation resistance and trigger alarms when it drops below a set threshold.
