Voltage Problems

Voltage problems relating to the quality of electrical supply can involve many aspects of the electricity network; from the type and condition of the power lines, to the lack of transformer capacity.

If you have concerns about the quality of your supply, it is helpful to document as much information as possible, to help our staff investigate the problem.

Typical types of problems:

  • Lights changing in brightness when appliances switch on or off
  • Lights generally dim
  • Computers restarting/crashing
  • Light bulbs frequently ‘blowing’
  • Problems with cooking equipment e.g. slow cooking
  • Motor starting/unexpected trippings
  • Equipment slowing down.

Please note that sometimes it can be difficult to identify the cause of the problem quickly, and in some cases problems can be attributed to more than one fault on the network and/or on the customer’s service line or main.

All problems are initially treated as a fault and should be referred to PowerNet’s System Control, phone 0800 808 587.  A PowerNet faults Team will be dispatched to investigate.  In many cases the faults contractor can locate and fix the problem.

If the problem cannot be immediately rectified, System Control will advise a PowerNet Engineer who will contact you to begin the investigation.
