Knaresborough, UK

Knaresborough Data Centre

We were commissioned to carry out the HV and LV Selectivity Study and Arc Flash study for the Knaresborough Data Centre. The objective was to provide a completed report giving its findings for a short circuit study to comply with BS EN 60909 and the Grading (Selectivity) for the distribution system to the facility. The study provided a list of settings as a result.

For the study, a visual survey was carried out on the existing relays and protection, intended for retention during the works.

Our services and solutions:

  • The identification of the type and electrical characteristics of the utilities including impedance, and protective device settings serving the HV and LV electrical distribution systems.

  • Understanding and establishing the incoming fault level

  • Carrying out the study accordingly the step-down transformers

  • To work with present relay manufacturers to establish the correct method to set its relays and to provide

  • an appropriate study with time current curves to suit.

  • To establish all relay, trip unit types and settings available.

  • To undertake breaker and relay settings including time current curves for both earth fault and overcurrent at HV and LV.

  • Arc Flash Study

  • Review of the UPS used to include type and requirements

  • ETAP soeware and/or Amtech software
