Not reported.
- Transformer failures on distribution networks can interrupt supply across several communities at once, so outage communications should cover all affected areas.
- Early public reporting of such events often lacks cause information, and operators should expect to follow up with confirmed findings.
- Inspection and condition monitoring of ageing transformer equipment can help identify failure risks before supply is lost.
