OPR 45 Early Streamer Emission Air Terminal
OPR45 Early Streamer Emission Air Terminal from ABB
ABB have developed the OPR range of early streamer emission air terminals as an alternative to the Helita brand.
These state-of-the-art technologies have been designed on the basis of a series of patents registered jointly by HELITA and the French National Scientific Research Centre (CNRS). The OPR is equipped with an electronic device which is high
pulse voltage of known and controlled frequency and amplitude enabling the early formation of the upward leader which is then continuously propagated towards the downward leader in an attempt to capture a lightning stroke. For full information please refer to ABB catalog available on request.
