Black building emergency power test BIT-1

05-12-2023 05:00:00 - 05-12-2023 09:00:00

Urgency: Planned
Affected services: Colocatie BIT-1
Impact: Main power grid BIT-1
Customer intervention required: No
Reference number: 188355

Summary:

On Tuesday, December 5th between 5:00 hrs and 7:00 hrs we will perform a black building emergency power test at BIT-1.

Details:

During this maintenance, we will switch off the main power grid for the entire location BIT-1 for 60 minutes, in order to test our emergency power systems. During this test, engineers of BIT will be monitoring the situation on multiple locations and will, if the need should arise, intervene. We will perform a deep battery discharge test in the days leading up to the black building test. This is done because we will also run on battery before running on power generators. This discharge test will be performed on both feeds separately.

 

Update 06:55:

During the blackbuilding emergency power test, at the step of switching back to the regular power supply, a problem was detected. The fuses in the transformer may need to be replaced. The supplier has been contacted and is expected to be on location within 2 hours.

We have therefore extended the maintenance window to 10:00. There is no interruption in the power supply, we are currently running on emergency power supply.

 

Update 08:51:

The supplier (Liander) replaced the fuses in the transformer on site and the switch to mains voltage has been successful. We hereby close the maintenance window.
