Harmonics - fighting the enemy from within
01 December, 2009 by Paul Stathis
The push for ‘greener’ electricity through more sophisticated electrical technologies has, in many cases, increased the negative consequences of harmonics on our electrical infrastructure. Electronic ballasts for lighting, switchmode power supplies for PCs and variable speed drives for motor controls are becoming ubiquitous in our homes and workplace. But while they’re improving our energy efficiency, they’re also making the electricity supply dirty.
