Blade Inspection

Reduce Repair Costs

Avoid more expensive repair or blade replacement by identifying the turbines that need immediate inspection for possible lightning damage with the help of Blade Inspection reports from DTN.


Accurate daily lightning reports.

WeatherSentry combines the best global lightning detection networks with automated intelligence and meteorological support to generate a daily report you can use at each wind farm to do a proactive inspection.

  • Reports include the turbines that were in close proximity to lightning strikes as well as details about each strike–distance, amperage, polarity, time and location.
  • Get real-time inspection alerts sent to your operations center to determine whether to restart turbines after a fault or inspect it first.
  • All lightning data from inspections is permanently archived in a database you can query at any time.


Create a plan for safe repair.

Stay ahead of potential maintenance issues. Better-informed decision support will catch issues before they become big problems.

  • Repair blade damage in place before the damage can propagate and cause a far more expensive repair or even full blade replacement.
  • Minimize generation loss due to turbine shutdown due to blade failure.
  • Use the lightning event archive to create inspection punch lists for any timeframe; submit warranty or insurance claims; analyze the frequency of turbine strikes and see what turbines warrant additional lightning protection investment and review inspection activities over any time period.

Blade Inspection Frequently Asked Questions

YesDTN has access to and ingests insight from global lightning detection networks.

Yes. When you sign up for the service, all reports generated are archived and can be queried. Lightning archiving displays lightning stroke data for the past 72 hours. Detailed information on time, latitude, longitude, and amplitude allows the user to document, analyze, and report on lightning activity for damage prevention, analysis, planning, insurance claims, etc.

DTN not only provides Blade Inspection but through WeatherSentry Wind Edition, includes unique weather visualizations accurate forecasts, including hub height wind speeds, weather alerts, and meteorological consultations.
