| Maintenance of protective measures |
 |
This Recommendation gives guidance on the maintenance of protective measures (protective devices and assemblies and their earthing) in telecommunication installations. It deals with the maintenance of the protection of telecommunication equipment, installations and cable plants exposed to the results of external sources of interference such as overvoltages and overcurrents due to lightning discharges or power induction. The maintenance activity is achieved with visual and complete inspections during periodical controls defined by this Recommendation. The complete inspection includes the visual inspection and additional measurements or investigations.The purpose of the maintenance activity is to control the effectiveness of the protective measures against overvoltages and overcurrents - to avoid or reduce hazard to people, damage to installations and disturbances to systems - taking into account the corrosion effects. The effectiveness of the protective measures against corrosion is also considered. |
