Abstract: A protection arrangement for inaccessibly located power distribution equipment includes a first enclosure with power equipment and sensors, a second enclosure adjacent the first enclosure and including a signal handling device, at least one sealed electrical conductor passage between the first and second enclosures, each comprising at least one penetrator through the walls of the first and second enclosures. The signal handling device in the second enclosure is connected to the sensors in the first enclosure via electrical conductors passing through said sealed electrical conductor passages and to an external protection device via a communication link. The signal handling device receives electrical sensor signals from the sensors and shapes them for submission to the external protection device.
