What happened

A headline on Eskom's website reports that a transformer tripped amid repairs at the Sebokeng substation and caused a supply interruption. The available text does not say how wide the interruption was, whether equipment was damaged, or whether anyone was hurt.

Contributing factors

The headline says the trip occurred amid repairs. No further cause is stated.

Lessons learned

A transformer trip during repairs can interrupt supply even when the work is planned.
Switching and protection arrangements should be confirmed before and during substation repairs.
Notices should state the area affected and when supply is expected back; this headline does not.
