This OPR range delivers improved performance in early streamer initiation and propagation, and represents further progress in terms of lightning protection, operating autonomy and ease of maintenance.

Small Equipment (No External Dimension More Than 50 cm)

ABB — already a leading global provider of lightning protection systems — reached a new milestone recently with the announcement that UL has granted certification for OPR 30, OPR 45 and OPR 60 Early Streamer Emission Air Terminals.

To protect the systems against the transient overvoltage (lightning).

The radius of protection (Rp) of the OPR is calculated according to the NF C 17-102 (edition 2011). It depends on the OPR efficiency (ΔT) expressed in micro-seconds. The maximum value for ΔT is 60 µs. The risk assessment shall be calculated according to the NF C 17-102 Annex A /

OPR 60 OPR: the high pulse voltage, early streamer lightning air terminal. In ongoing collaboration with the CNRS (French National Research Organization), ABB continues to innovate and has developed a new generation of lightning protection devices – the OPR early streamer emission (ESE system).

OPR Early streamer emission is based on the difference (ΔT), measured in a laboratory, in between the emission time of the OPR and the one from a simple rod. The OPR ESE air terminal is composed of a striking point connected to a down conductor to conduct the lightning to the ground. Upward leaders Meeting point Without OPR With OPR

OPR early streamer emission (ESE) air terminals are especially effective for lightning protection of industrial sites, administrative or public buildings, monuments and open-air sites such as sports grounds. During a storm, when propagation field conditions are favorable, an OPR ESE air terminal will generate an upward leader.
