A VS1 diamond is a high clarity grade with no visible inclusions and only small, hard-to-identify inclusions, whereas VS2 diamond will have eye-visible inclusions only 5 percent or less of the time. Know about the difference as …
FAQ: What are current source inverters and voltage source inverters?
A key difference between CSI drives and VSI drives is their energy storage method. CSI drives use inductive energy storage—that is, they use inductors in their DC link to store DC energy and regulate current ripple between the converter and the inverter. ... Because of the additional components, CSI drives are typically non-integrated ...

Difference between Horizontal Shaft Impactors and Vertical …
In summary, the main difference between VSI and HSI impactors is the direction of the impact forces they produce. HSIs use a horizontal shaft to deliver a powerful impact force to the material being crushed, while VSIs use a vertical shaft and centrifugal force to throw the material against a fixed surface.
