Scheduled
Dear Customer,
Following on from our POSTPONED broadcast sent out on the Friday 29TH October. Please be aware of the following confirmed re-scheduled essential maintenance being carried out at our South London Facility.
WHAT
As part of Pulsants planned maintenance regime, it is necessary for us to undertake an Annual Darken Building Test on site, to ensure all infrastructure works correctly in the event of a full loss of mains power. In parallel with this we are working with our HV contractor and undertaking the annual Inspection of our Transformers and Ring Main Units on site, so that we minimise impact and risk to the business and our customer base.
SERVICE IMPACT
NONE - No interruption or disruption to service is expected during these essential works, however due to the level of switching that will be undertaken during executing our Darken Building Test procedure, we are issuing a courtesy At Risk notification to all our customers.
WHY
The Annual Darken Building Test forms part of our stringent maintenance regime and this is to ensure all infrastructure works correctly in the event of a full loss of mains power to site.
To do this we will be working with our 3rd party contractors and the electricity company to isolate the mains power to the site and perform essential testing of our HV and LV infrastructure.
During this period, it will be necessary to run the site on generators. Pulsant will follow our Darken Building Test procedure, which will isolate each of the incoming utility supplies to site. In parallel with this the Transformers and Ring Main Units will also be inspected and serviced.
The testing will be completed by Pulsant staff and a number of specialised 3rd party contractors.
All diesel supplies to the site have been checked and confirmed adequate supplies, reserve supplies are on standby. Once works have been completed, the fuel supplies will be replenished accordingly.
We have provisioned a maintenance window of up to 8 hours to allow us an adequate time window to complete all the necessary tests. All personnel will remain on-site during this maintenance window and for a period of up to 1-hour post the maintenance being completed window.
Works are expected to be non-service affecting as customers will remain on UPS protected supplies whilst the Generators take up the load on one feed (the other will remain unaffected) and then remain on Generator load (in an N+1 configuration) until all testing has been completed. This maintenance does involve changes to power source to the site, hence an At Risk notification is being sent out.
Pulsant has been preparing extensively for this scheduled Darken Building Test.
We will have a number of different contractors and Pulsant personnel on site including expert contractors to support our Generators, UPS devices, electrical infrastructure and most importantly Pulsant network and site support staff. We have worked with the electricity utility supplier to mitigate risk as far as possible, below is the planned approach with regards to completing all necessary works and undertaking this Annual Darken Building Test
WHEN
To mitigate risk and impact, Pulsant have scheduled for these works to be carried out at the weekend.
Pulsant confirm that the maintenance window is noted below and the associated At Risk period:
Saturday 18th of November 2017, commencing at 10.00 GMT and completed by Saturday 18th of November 2017 by 18.00 GMT.
The At Risk window will be kept to an absolute minimum and the site will have utility mains power restored and resuming full site protection at the earliest opportunity.
Please accept our sincere apologies for any inconvenience this may cause.
Regards,
Pulsant Support Team
