Digital lightning check
Lightning protection systems must function - every day, 24 hours a day. This is because lightning can strike at any time or surge voltages can occur. However, it is not always easy to see when the system has arrested lightning and surge voltages successfully. Here, the new LSC I+II lightning current meter from OBO Bettermann provides reliable support. This is because the device measures and permanently saves pulse currents, together with the date and time. Thus, you can use the practical LCD display to check whether lightning has struck the lightning protection system. Should this be the case, then the lightning protection system must be maintained according to VDE 0185-305 (IEC 62305), to ensure that it is not damaged.
Thanks to its protection rating of IP 65, the lightning current meter is suitable for indoor and outdoor use. The corresponding cable clips allow installation on round cables or flat conductors. The meter can be mounted directly on the arrester or on the PE cable of the surge protection device. Long, maintenance-free use of the devices is possible, thanks to the internal lithium batteries with their long lifespan.
