    5 Extra information on operation of the DVLD 5.1 Averaging time & distance thresholds Independently of the Davicom’s settings, the DVLD’s internal circuit is always operating and actively listening for the electromagnetic signature of lightning strikes. It can detect both cloud- to-ground and cloud-to-cloud strikes.

    40 km, it will output this number to the Davicom unit for further action. Actually, the Davicom unit reads the data out of the DVLD once every second. It is important to note that this averaging and distance estimation takes place on a 17 minute cycle in the hardware.

    For DV-Mini or DV-2-8/216 units, the control could also take the form of sending an SNMP trap or performing an SNMP SET. If you wish, the Davicom can also be configured to send an alarm when the Distance Trigger event occurs, in addition to the local control commands. The example below shows an e-mail address configured as an alarm destination.

  • Page 13: Hands On Setup

    To achieve this dual-threshold capability, it is necessary to use the Metering Math Functions built-in to the Davicom units. The MMF’s have two-level alarm capability built-in. The example below shows that a Minor Alarm has been set for a minimum distance of 30 km and a Major Alarm has been set for a minimum of 10 km.

  • Page 15: Logging

    7.3 Logging The DVLD and Davicom units can also be used to log lightning storm activity in the vicinity of your site. The data can be transferred at periodic intervals and compiled in Excel to produce a chart of storm activity and proximity to the site. The figure below shows the DVLD range data of a real thunderstorm that passed right over our offices in the evening on June 18 2015.
  • Page 16 Firstly, the « Custom Log » box must be checked as shown below. Then, the Custom Log can be configured as shown below to transfer the log by e-mail when it reaches 90% capacity. The Data logging must be activated to take periodic samples (every 5 minutes in this example).
