Predictive Maintenance (PdM) Predictive Maintenance is based upon knowing the condition of equipment in a system. Predictive Maintenance means using technologies that tell us what will fail in the future, not what is failing right now. Predictions come from monitoring the condition of equipment as it is operating. Visual Detection Infrared Detection Ultrasonic Emission Detection RF Emission Detection There are many benefits to conditions- based maintenance including lowering cost, improving system performance and enhancing worker safety. But, how can the condition of all the equipment on the grid be measured? Measuring the Condition of the Grid  Here are some ways to measure equipment condition. 

Exacter Acquisition and Analysis Process Data Acquisition & Discrimination Data Analysis Actionable Information RF emissions from arcing (deteriorated) electrical components Exacter sensor in vehicle/aircraft collects the signals and then discriminates and GPS locates arcing, tracking and leaking electrical components Data analyzed for severity, persistence and prevalence, enabling: Exact locating of failing component Replacement prioritization Precise GPS coordinates and relevant condition- data transmitted to servers for final statistical geospatial analysis Reports and GIS compatible information provided to customer

The Need: DOE Smart Grid Project Example

Condition Assessment: Select Circuits and Design Survey Following the selection of circuits to be included in the assessment, Exacter Data Specialists design specific survey routes using public access roadways. The EXACTER Sensor is sensitive in a 200 meter radius from the vehicle.

Survey Quality Control Condition Assessment: Monitor Survey Progress While the survey is underway, the path of the survey vehicle, the WHITE trace, is monitored to insure that the circuits being assessed are completely studied. Accuracy of results is improved by multiple passes of the same route over a four week period. While the survey is underway, the path of the survey vehicle, the WHITE trace, is monitored to insure that the circuits being assessed are completely studied. Accuracy of results is improved by multiple passes of the same route over a four week period.

Condition Assessment: Real-time Failure Signature Analysis Whenever the EXACTER Sensor locates a line emission that correlates to a Failure Signature a real-time study is completed. The 986 RED markers show all of the studies from the four-week survey process.

Condition Assessment: EXACTER Condition Assessment Results The 986 RED Failure Signature Events are studied by EXACTER Servers to create this result: 25 BLUE Maintenance Groups where a structure includes at least one weakened component.

Deteriorated Equipment Impact on Grid Resiliency 1. THE GRID IS OLD—AND IT'S ONLY MAKING MATTERS WORSE According to the DOE report: "70% of the grid’s transmission lines and power transformers are now over 25 years old and the average age of power plants is over 30 years." As a result, "the age of the grid’s components has contributed to an increased incidence of weather-related power outages.“... Utility Dive
