Method for detecting or predicting an electrical fault
A method of predicting an electrical fault in an electrical network, wherein a signal indicative of a transmission is received, compared to a reference signal, a determination is made and if the comparison suggests a fault, indicating the determination of the fault.
1. A method of detecting and predicting an electrical fault in a node, the method comprising:
transmitting a transmission signal on the node;
generating a reference transmission signal of the transmission signal;
receiving a monitor signal indicative of an actual transmission signal for the transmission signal on the node;
comparing the monitor signal to the reference transmission signal;
determining a fault when the comparison satisfies a fault threshold; and
indicating the determination of the fault by at least recording the fault for subsequent retrieval.
2. The method of claim 1 wherein the receiving comprises receiving the monitor signal in real time with the transmission signal.
3. The method of claim 1 wherein the receiving comprises receiving the actual transmission signal as the monitor signal.
4. The method of claim 1 wherein the reference transmission signal is linked to the transmission signal.
5. The method of claim 1 wherein recording the fault comprises storing the fault in a memory device.
6. The method of claim 1 wherein the comparison satisfying a fault threshold comprises the monitor signal lying outside a fault threshold range.
7. The method of claim 1 wherein the comparison satisfying a fault threshold comprises the monitor signal being greater than a high fault threshold.
8. The method of claim 7 wherein the comparison satisfying a fault threshold comprises the monitor signal being less than a low fault threshold.
9. The method of claim 1 further comprising clearing the fault after the indicating.
