Power Quality

FAQs

 

For electrical systems to function in their intended manner without significant loss of performance or life, they require a supply of electricity that is of good quality. Good quality electrical power has the following characteristics:

 

  • It must have a continuity of service (not be interrupted). 
  • It must have a very low Harmonic content.
  • It must have a very low variation in the voltage magnitude.
  • It must have very low transient voltages and currents.

 

The term ‘clean power’ is used to describe electricity that is considered to be of good quality (see above) with particular reference to a very low harmonic content. Therefore, the term ‘dirty power’ is used to describe electricity that is considered to be of low quality (opposite to the above) with particular reference to a very high harmonic content.

In Australia, our electricity is supplied in alternating current at a frequency of 50Hz. In alternating current (AC) the movement of electric charge periodically reverses direction. In direct current (DC), the flow of electric charge is only in one direction. 50Hz means that the AC has a frequency of 50 cycles per second. This is also known as the ‘fundamental’ frequency. AC is the form in which electricity is delivered to businesses and residences. Most electrical devices (such as motors) need clean electricity to function properly. This means that the electrical supply needs to be a clear
sinusoidal wave.
