What happened

A fire at Kloofsig substation in the early hours of Wednesday affected power supply to Kloofsig and Lyttelton. The City of Tshwane said technicians made significant progress overnight, including completing installation of switchgear and cable termination. Rain delayed the work. Restoration also involved cable identification and termination at Barnard Park substation, identification of feeder cables from Lyttelton and Die Hoewes, and planned testing. When power would be restored had not been stated in this report.

Contributing factors

The cause of the fire was not reported. Rain was reported to be delaying restoration work.

Lessons learned

  1. A substation fire can cut supply to neighbouring areas until alternative feeders are identified and joined.
  2. Restoration after a substation fire must allow for weather delays such as rain during cable work.
  3. Cable identification and testing at several sites reduce the risk of energising the wrong circuit.

More lessons on outages, backup supply and restoration, weather and external hazards, electrical protection and isolation, from every incident on the register.
