Lightning Sensor & Analyzer

Lightning strike

Lightning curve

A typical lightning strike is characterized by the general waveform as shown here. The Lightning Sensor & Analyzer detects and measures the lightning induced wave-form and features native interfacing with turbine management systems to send detection statistics and alarms.

When evaluating potential lightning damage to a structure, four key parameters are of interest:

  1. Peak current
  2. Rise time
  3. Specific energy
  4. Total charge

In addition to Jomitek’s well established capability for reliable lightning strike detection, the next generation Lightning Sensor & Analyzer offers advanced measurement of these four lightning strike parameters along with comprehensive analysis and logging capability. This enables a deeper understanding of the dynamics behind lightning strikes that causes damages. This enables selective service visits based on an emperical evaluation of reported key parameters of a strike. Please see the LSA datasheet for detailed information.
If you want to learn more there are several of other relevant documents on our product information page, for example white paper discussing the immunity against nearby lightning.

The sensor itself is easy to mount and requires a single IP67 Ethernet cable as a combined interface for Ethernet communication, power supply and alarm relay signaling. The sensor hosts an advanced post-processing platform including storage capability for thousands of lightning strikes, a web server which provides easy manual configuration and inspection of lightning events, FTP support, and a number of options for automated configuration and measurement retrieval for large installations.
