System design |
The stadium is fed by a primary source. Ideally, a fully independent secondary source should be available, e.g. in a ‘open half-ring’ grid design. In addition to the primary source for the floodlights in the ‘normal’ operation mode, a backup system must be available to power up the floodlights back to 100% within 1 minute. The backup system could be designed either with a diesel generator that is started up when the power failure occurs or a secondary source with a fully automated switchover. |

System functionality |
In the normal operation mode, the primary source must be able to provide power for the full illuminance level required. If the primary source fails, a backup / secondary system must be able to supply power to achieve a 100% recovery within 1 minute. Switching back from the backup mode to the ‘normal’ operation must be manually controlled from the moment the full primary power supply is recovered. |
