Lightning Sensor & Analyzer

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.

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.
