METHOD OF MULTI-LEVEL FAULT ISOLATION DESIGN
First Claim
Patent Images
1. A method of isolating a fault condition from many potential fault conditions comprising:
- generating a group of potential faults based on a plurality of measured parameters;
selecting a first isolator from a plurality of isolators based on performance of the first isolator in differentiating between potential faults within the group of potential faults;
redefining the group of potential faults to include fewer potential faults than the previous group of potential faults based on criteria applied by the first isolator; and
reporting a fault condition responsive to the redefined group of potential faults including one potential fault.

9. A fault isolator for determining a fault condition of a system comprising:
-
a receiver for receiving parameter data indicative of system performance; a controller receiving data from the receiver, the controller including, a first isolator for differentiating between at least two potential faults from a group of potential faults indicated by the received data;
a second fault isolator different than the first isolator for differentiating between potential faults not discernable by the first isolator; and
a communication device for communicating the fault condition determined by criteria of the first and second isolators. - View Dependent Claims (10, 11, 12)
