Davicom Counts Lightning Strikes

How many hits did your tower take in that storm? Now you’ll know

Davicom will exhibit at the NAB Show, and will feature its DVLC-1 Lightning Counter, part of its Lightning-Awareness line. 

 It detects and counts the actual lightning strikes sustained by a transmission tower or grounded structure.

It uses a magnetically-coupled current detector to sense and count lightning-induced pulse currents flowing to ground.

Davicom says the DVLC will safely signal a Cortex unit whenever the tower is hit by lightning. This functionality gives site operators better situational awareness of the reasons why their site may have stopped transmitting, or even better, that the site is still on-the-air despite receiving a hit.

The DVLC can also be used as a functional indicator of a site’s ground system status. If lightning hits and the ground circuits handle the load properly, operators can be confident that their site is protected.

The DVLC can be used independently from Davicom RTU products. It comes in two parts.

The current sensor (shown, with cable) is designed to be mounted on one of the tower legs or ground wires and it detects lighting-induced current pulses. These pulses are converted to an optical signal for safe, electrically-isolated transmission through a fiber-optic cable to the optical detector.

The optical receiver (blue-plated box) is mounted inside the shelter and produces a relay closure every time the detector sends a pulse down the optical cable. These relay closures can be counted and compiled with a non-volatile counter, or with any Davicom Cortex unit.
