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

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.
![Page 9: GIS Integrated Analytics for Preventive Maintenance and Storm … · 2013-07-20 · 5,950 OVHD Miles. Example: Prioritized Worst Performing Circuit (WPC) Improvement Program . 73%](https://reader033.fdocuments.in/reader033/viewer/2022041910/5e66f2705393b46154190a34/html5/thumbnails/9.jpg)
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.
![Page 10: GIS Integrated Analytics for Preventive Maintenance and Storm … · 2013-07-20 · 5,950 OVHD Miles. Example: Prioritized Worst Performing Circuit (WPC) Improvement Program . 73%](https://reader033.fdocuments.in/reader033/viewer/2022041910/5e66f2705393b46154190a34/html5/thumbnails/10.jpg)
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.
![Page 11: GIS Integrated Analytics for Preventive Maintenance and Storm … · 2013-07-20 · 5,950 OVHD Miles. Example: Prioritized Worst Performing Circuit (WPC) Improvement Program . 73%](https://reader033.fdocuments.in/reader033/viewer/2022041910/5e66f2705393b46154190a34/html5/thumbnails/11.jpg)
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.

Prioritized Maintenance Action: Select Equipment to Replace
Specific component(s) that are arcing, leaking
