Davicom’s Lightning Awareness Products

DVLD Lightning Detector and DVLC Lightning Counter

Davicom’s award-winning DVLD-1 lightning detector is designed to give you advance warning of the presence and approach of potentially hazardous lightning activity in its vicinity. It uses a receiver and a sophisticated statistical algorithm to analyze electromagnetic signals and to provide an estimate of the distance to a storm, from as far away as 40 miles (65km).

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 your transmission tower or grounded structure. It uses a magnetically-coupled current detector to sense and count lightning-induced pulse currents flowing to ground.

How can you benefit from having a Lightning Awareness System with Automated Alarms and Controls?

Lightning Detector (DVLD-1)

The DVLD’s storm warning alarm can be used to automatically prepare your site for 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.

Important communications links can also 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.

The Lightning Strike Counter (DVLC-1)

The DVLC will safely signal a Cortex unit whenever your tower is hit by lightning. This functionality gives you better situational awareness of the reasons why your 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 your site’s ground system status. If lightning hits and the ground circuits handle the load properly, then you can be confident that your site grounding is operating as expected.

Built for Demanding Applications

Davicom’s Lightning Awareness Products can be used for application where lightning strikes can be a threat to system operations. Taking advantage of the system’s flexibility, you can configure the system to automatically activate controls and trigger a siren, a strobe, or shut down sensitive equipment.

It can also give you better situational awareness by measuring temperatures, wind speed, humidity, and many more parameters that can help you “fill in the blanks”. In short, these versatile lightning awareness products can be used in mines, for telecommunication installations, schools, hotels, public pools, and sport complexes to notify people and trigger actions when a storm is within range.

Monitoring, Control & Automation

Directly connect analog sensors or status contacts, and control devices through relays, SNMP or MODBUS.

Level & Pressure

Thanks to its flexible input circuits, the Cortex can add even more value to your lightning awareness system by allowing you to connect to almost any type of analog device such as temperature, humidity, wind speed, and other environmental sensors.

Activate a physical relay, a MODBUS device, or send SNMP commands/notifications to any equipment on your network. These commands can also be initiated through schedulers, timers or through logical conditions that you set up.

Alarms & Notifications

Receive Alarms & Notifications in Real-Time When a Lightning Storm Approaches.

Alarm notifications can be sent to you by Email, SMS, voice telephone call, PA audio or PTT radio. Up to 32 custom vocal messages can be stored in the device and transmitted by these various means. Major and minor alarms can be differentiated and a smartphone app is available to receive push notifications when an alarm happens.

LOGs & Real-Time Data

Keep Track of Your Real-Time & Historical Data

Real-time data is available to you at any time, thanks to the Cortex Series’ HTML5 web interface. Historical data can also be extracted as reports or sent to you by email or FTP download on a regular basis. Storm-distance sampling time is configurable according to your requirements and can be stored on a USB memory stick locally at the site.

The complete Web-based, HTML5 GUI allows you to customize display screens to your liking, or according to the devices you may want to use to connect to the site. Below is an example:

Sensor Hardware

Lightning Detector (DVLD-1)

The DVLD is made up of an antenna/receiver module that is usually installed outdoors to ensure better signal reception. A weatherproof cable connects the device to one of the Cortex’s USB ports. The DVLD cannot be used without a Davicom unit.

Sensor Hardware

The Lightning Strike Counter (DVLC-1)

The DVLC can be used independently from Davicom products. It comes in 2 parts:

  1. The current sensor 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.
  2. The optical receiver is usually mounted inside the shelter and it produces a relay closure every time the detector sends an optical pulse down the optical cable. These relay closures can be counted and compiled with a non-volatile counter, or simply with any Cortex unit.
