Transformer fire cuts power to various parts of Pretoria and Centurion

Aren't these substation fires caused by them not replacing the transformer oil which is a required maintenance item to prevent fires apparently as old oil forms water condensation which shorts **** out and thats how it starts, especially after a cool down period like loadshitting.

My dad used to work for a company that used to purify the oil and then return it back to the transformer all while it was still operational. That was back in the 90s when maintenance was still a thing...I think there are also silica filters on some transformers as well meant to soak up the moisture from the air.

Makes sense. All you need really is a water sperator.
