Signal handling for inaccessibly located power equipment
First Claim
1. A protection arrangement for inaccessibly located power distribution equipment, the arrangement comprising:
- a first sealed enclosure comprising;
power equipment; and
a group of sensors sensing physical properties of the power equipment, the first sealed enclosure being sealed to provide a closed environment for the power equipment; and
a signal handling device connected to at least some of the sensors and to an external protection device via a communication link passing through at least one sealed communication link passage,wherein the signal handling device is configured to receive electrical sensor signals from the at least some of the sensors and shape the electrical sensor signals for submission to the external protection device, andwherein the external protection device has a connection to protection elements in the first sealed enclosure and is configured to receive sensor signals, analyse the sensor signals, and send one or more protection control signals for controlling one or more of the protection elements in the first enclosure if the analysis indicates that protection is needed, andwherein the protection elements are circuit breakers.

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.
