Abstract

A system and method for providing monitoring of industrial equipment is disclosed. In such a system and method, one or more sensor units may be configured to generate output signals conveying information regarding power conducted to the industrial equipment. One or more power parameters may be determined based on the sensor output signals. Abnormal operations of the industrial equipment may be determined based on the power parameters and alerts responsive to the abnormal operations may be generated. In some embodiments, information regarding a present operation of the industrial equipment may be received from a control system and/or monitoring system. In those embodiments, a fault or a likelihood of fault of the control system and/or the monitoring system may be determined.

a first sensor unit configured to be coupled to a first power line that conducts power to a first piece of industrial equipment, the first sensor further being configured to generate output signals conveying information related to the power conducted through the first power line to the first piece of industrial equipment; and

one or more processors configured to execute computer program modules, the computer program modules comprising;

a parameter module configured to determine one or more power parameters of the power delivered through the first power line to the first piece of industrial equipment;

an analysis module configured to identify abnormal operation of the first piece of industrial equipment by comparing a first power parameter of the power delivered through the first power line to the first piece of industrial equipment, as determined by the parameter module, with a first threshold and/or pattern; and

an alert module configured to generate an alert responsive to the identification of abnormal operation of the first piece of equipment by the analysis module.

2. The system of claim 1, wherein the first sensor unit is separate and discrete from the first piece of industrial equipment, and is separate and discrete from any control and/or monitoring system configured to control and/or monitor the first piece of equipment.

3. The system of claim 1, wherein the analysis module is configured such that the first threshold and/or pattern is determined dynamically based on information about present operation of the first piece of equipment.

4. The system of claim 3, wherein the analysis module is configured to receive information about a present operation of the first piece of equipment from a control and/or monitoring system.

5. The system of claim 4, wherein the analysis module is further configured to identify a fault or a likelihood of a fault of the control and/or monitoring system based on the information about the present operation of the first piece of equipment received from the supervisory control and data acquisition system and the power parameters determined by the parameter module.

6. The system of claim 1, further comprising a second sensor unit configured to be coupled to a second power line that conducts power to a second piece of industrial equipment, the second sensor further being configured to generate output signals conveying information related to the power conducted through the second power line to the second piece of industrial equipment, wherein the parameter module is further configured to determine one or more power parameters of the power delivered through the second power line to the second piece of industrial equipment, wherein the analysis module is further configured to identify abnormal operation of the second piece of industrial equipment by comparing the first power parameter of the power delivered through the second power line to the second piece of industrial equipment, as determined by the parameter module, with a second threshold and/or pattern, and wherein the alert module is further configured to generate an alert responsive to identification of abnormal operation of the second piece of equipment by the analysis module.

7. The system of claim 1, wherein the analysis module is further configured to identify abnormal operation of the first piece of industrial equipment by comparing a second power parameter of the power delivered through the first power line to the first piece of industrial equipment, as determined by the parameter module, with a second threshold and/or pattern.
