To control a motor of 1,000HP or less, 480V VFDs are equally as effective as their medium- voltage counterparts. AND they’re also much less expensive to purchase and operate.
Have you ever paid lots of money for a product that failed to perform? Perhaps you bought a carpet cleaner that left stains? Or a sleeping pill that kept you awake? How about a weight-loss miracle that actually added pounds?
Electrical harmonics are a big problem in the oilfield. Every device connected to the grid is susceptible to harmonic interference and low power quality. Worse, harmonic distortions do not discriminate between residential and industrial users.
In today’s cost-sensitive environment, it is more important than ever to improve your field’s efficiency and look at the overall economics. By using SPOC drives, a project originally budgeted at $25 million comes in around $8 million. Is saving $17 million on a project possible by using SPOC drives? Watch the video and see how the results speak for themselves.
Harmonics are a harmful condition that can occur in electrical environments. Ideally, electricity is delivered at a set and sustained frequency—typically 60Hz in the US. Realistically, disturbances and distortions occur that add frequencies to the electricity. Harmonics are propagated both downstream to equipment and upstream into the power grid. The effect on the grid depends on the severity of the harmonic distortion and the size of the total energy pool.
