Davicom’s award-winning DVLD-1 lightning detector is designed to give advance warning of the presence and approach of potentially hazardous lightning activity in the vicinity of a transmission site. It uses a receiver and a sophisticated statistical algorithm to analyze electromagnetic signals and to provide an estimate of the distance (up to 40 miles, or 65 km) to a storm.
This storm warning signal can be used to automatically prepare the site against potentially destructive lightning strikes by, for example, starting up the generator, waiting for it to stabilize, and then disconnecting from utility power while the storm passes-by. Smoother site operation is therefore ensured by avoiding chaotic switchovers during a lightning-induced power failure. In addition, important communications links can be protected by temporarily disconnecting them during passage of the storm, thereby ensuring they will still be available for critical communications once the storm has passed.
Davicom’s DVLC-1 Lightning Counter is the perfect complement to the DVLD-1 Lightning Detector. The DVLC-1 detects and counts the actual lightning strikes sustained by a transmission tower.
It is designed to be mounted on one of the tower legs and, thanks to its magnetic pulse detector and fiber-optic cable, will safely signal the Cortex whenever the tower is hit by lightning. This functionality gives site operators better situational awareness as to the reasons why their site may have stopped transmitting, or even better, that the site is still on-the-air despite receiving a hit!
