Electricity Quality and Meters
Power Supply and Quality
New Zealand's electricity supply must be maintained at constant levels. This means that electricity generators must ensure enough electricity is sent through transmission lines to meet the needs of all consumers.
The amount of electricity in the lines must be kept at a constant level of volts. If this is not controlled or monitored, electrical appliances can be seriously damaged.
When too much electricity is provided this is called a surge. An surge protector can prevent this surge reaching expensive electrical appliances reducing the risk of damage.
Electricity Meters
Your electricity meter records the number of units of electricity you have used. On your electricity meter one unit equals one kilowatt hour (1 kWh). The total number of kilowatt hours used is what is recorded by your electricity supplier.
Electricity retailers charge consumers based on the number of kilowatt hours used per month.
