Spike Protection

There are times when power unexpectedly fails. Cars crash into poles; animals or trees can fall onto power lines; and storms cause lines to clash - these events can all cause power cuts. Besides cutting power, such incidents can also send too much voltage through your power lines and cause damage household appliances.

Protection

• Protect your sensitive equipment from surges and spikes with a power filter or surge protector. They range in price from $10 to $200, and plug into your household power points. Most have three or four sockets, and some also filter out electromagnetic and radio frequency interference on the lines.
• If you are concerned about losing data on a computer during a power cut, consider an uninterruptible power supply (UPS). They have battery back-ups which maintain power supply while you shut your computers down.

Please remember, spikes and surges are rare, and most people will never experience one.

Northpower cannot be held liable for damage to appliances caused by surges and spikes because these can be unavoidable. However, do check whether your insurance policy provides coverage against such damage. Some insurance policies refer to the effects of spikes and surges as "fusion" and some policies do exclude this type of damage.

Power quality 

Small spikes and surges in power, and electrical 'noise' caused by other customer equipment can also affect electronics and cause minor damage that eventually leads to equipment failure. About 80% of power quality issues are actually caused by other equipment on the same premises, and they are often easily fixed. Power filters and surge diverters will help protect equipment from catastrophic events and also reduce unnecessary wear and tear.
