What is asset health monitoring?
Tracking how each asset’s condition changes over time — so problems are seen, ranked and acted on before they become failures.
Asset health monitoring brings together inspection findings, test results, fault history, age and monitoring-system data into one picture for each asset. Each asset is graded, and its readings are followed over time, because a trend shows more than a single reading.
Combining condition with the effect of failure on operations ranks the assets that need attention first. That guides targeted maintenance and gives asset planning the evidence it needs for renewal decisions. In AGL work the data typically includes insulation-resistance trend per circuit, constant current regulator (CCR) load and output current, lamp-out counts against serviceability limits and measured light output. Without it, failures come as a surprise and money is spent without knowing where it is needed most.
- Collect. Gather inspection findings, test results, fault and alarm history.
- Combine. Hold one consistent record per asset, with its age and operating hours.
- Grade. Give each asset a condition grade, such as good, watch or poor.
- Trend. Follow readings over time and note the rate of change.
- Rank. Combine condition with the effect on operations to set priorities.
- Act. Direct maintenance and renewal decisions, and feed the results back as new data.
Frequently Asked Questions
Q1What is asset health monitoring in airfield ground lighting?
The lifecycle activity that tracks how the condition of AGL assets changes over time. It combines data from inspections, tests, faults and monitoring systems into a picture of each asset's health, so problems can be seen and acted on before they cause failures.
Q2What data feeds asset health monitoring?
Inspection findings, test results such as insulation resistance and regulator current, fault and alarm history, operating hours and age, and information from control and monitoring systems. The more consistent the data, the clearer the picture.
Q3Why look at trends rather than single readings?
One reading says whether an asset is within limits today. A series of readings shows direction: a value that is still acceptable but steadily worsening warns of future failure and allows action to be planned.
Q4How is asset health used to set priorities?
Each asset is graded by condition and by how serious a failure would be for operations. Assets in poor condition that matter most to safe operations are moved up the maintenance and renewal programme.
Q5What is the link to predictive maintenance?
Where data show a clear pattern of deterioration, maintenance can be timed to the condition of the asset instead of a fixed interval. This helps avoid both unnecessary work and unexpected failures, though it depends on good data.
Q6How does it feed other lifecycle stages?
Condition and risk information goes to maintenance for targeted work, and to asset planning for repair, refurbishment, upgrade or replacement decisions. Results of that work come back as new data, and the cycle continues.
See It. Understand It. Then Learn How to Engineer It.
Recognising an AGL system visually is the first step. The next step is knowing how to design, install, test, commission and maintain them correctly.
