As ac drive usage increases, the amount of harmonic current will also increase, further straining the already stressed distribution grid. This will eventually force manufacturers to place more emphasis on purchasing ac drives that provide some means of harmonic mitigation. |
Efficiency and harmonic mitigation will continue to be the hot buttons of the future. However, as today's youth — who use computers, I-Pods, DVD players and cell phones with ease — enter the job market, they will demand the same ease of operation they are accustomed to. Operator interfaces will become the next hot button with these new engineers and purchasing authorities demanding drives that are just as easy to program as their cell phones or X-Boxes. |
They take way too much time ... (and do) little good. |
