Is this at all related to use of DC-power in datacentres?

  Afaik DC or AC can cause similar arc flashes. Typically you do need high voltages to bridge larger gaps.

    But ac will break the current at the alternating frequency and dc won't, so it is much harder to break a circuit with a high direct current. That's why monster movies have those huge knife switches.
