ABB OPR
DESCRIPTION
During a storm, when propagation field conditions are favorable, an OPR ESE air terminal will generate an upward leader. This upward leader from the OPR tip propagates towards the downward leader from the cloud.
The emission of an early streamer to a lightning event delivers a beneficial triggering time compared to a single rod air terminal exposed to the same conditions. This in turn drives the enhanced performance and protective distance achievable by ESE devices.
The beneficial triggering time is determined as the average time gained at the moment of sparkover, with efficiency confirmed by high-voltage laboratory testing. All ESE tests are defined in Annex C of the French standard NF C 17-102 (2011 Version).
This beneficial triggering makes OPR air terminals especially effective for the protection of industrial sites, administrative or public buildings, monuments and open-air sites such as sports grounds.
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). 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. These advancements reinforce ABB’s leading position in active lightning protection, with over 200000 installations worldwide.

ABB – MCB
Miniature circuit breakers (MCBs) ensure electrical safety in homes, offices and other buildings as well as for industrial applications by protecting electrical installations against overloads and short circuits. Once a fault is detected, the miniature circuit breaker automatically switches off the electrical circuit to prevent damage to wires and to avoid the risk of fire. Warranting reliability and safety for people and assets, MCBs are equipped with two tripping mechanisms: the delayed thermal tripping mechanism for overload protection and the magnetic tripping mechanism for short circuit protection.
