Around 2,500 people lost power yesterday and early this morning after a section of overhead power cables came down in the Wymondham and Long Stratton area.
UK Power Networks are still working to repair power supplies to 511 customers in the Silfield area.
The cables came down around 4.20am today but yesterday in Long Stratton another cable fault caused more problems including cuts and flickering lights.
UK Power Networks say this damaged another cable on the network supplying villages in the Wymondham area. Engineers are currently out in Norfolk trying to fix the problems.
