ANDORRA TELECOM installs an Autonomous Lightning Preventive Disconnection System.
Lightning strikes on or near the AC power input lines of the communications tower can damage both the telecommunications equipment and the power input circuits and their protection. Repairs to such damage can be costly, in addition to temporarily taking the Principality of Andorra's main communications tower out of service.
Solution
To minimize the number of incidents caused by lightning strikes, as well as to maximize the uptime of the communications tower, an Autonomous Preventive Disconnection System (SADP) has been installed that will automatically isolate the tower when a storm approaches and there is a potential risk to the Pic Carroi facilities.
The SADP is based on the information provided by the PREVISTORM® TWS thunderstorm warning system, with a customized and extended integration by this communications tower. The installed system uses information from two PREVISTORM® electric field sensors together with information obtained from a high precision lightning detection network to control a digital power sectioning system. For activity monitoring and control, the system also integrates lightning strike detection data from the tower using two DL EOLOS K15FO series lightning strike counters.
