I am please to see details on harmonics and power factor. NZ study of 200 homes shows we have very bad harmonic and power factor at site. If we can have a system that is on line at every home which will correct this problem and benefit everyone or we will continue to pay for the wasted in energy and create inductive system load for the Utility. This will or may change with new smart metering as each site can be monitored for kvar, and harmonics I am hoping. We in NZ do not really have a real/true sustainable and energy policy. Europe has a policy of reducing energy use of 20% by 20/20. We should have offered a grid connected PV instead the Transpower 400kV new line. Upgrade of over 70year old line would have been a better option plus a HVDC line. China has just completed with ABB a new HVDC line. Please outline in home and industry all the items of electrical equipment that causes all our power problems. Keep up the good work.
