Structures form after application to reduce flow and prevent sag.
Because voltage sags are so short in duration, power reliability technologies like generators, high-speed switchgear and standby uninterruptible power supplies are not fast enough to respond to sags and prevent downtime.
Each time, the unit would come back as NFF, or "No Failure Found," and with the help of the manufacturer, they finally determined that the root cause was voltage sags.
The results for the as-built test protocol need to be used as a range of values that can be encountered in field installations since nonuniform compression increases duct pressure loss above the values derived from the pressure loss equations for straight, natural sag, and maximum sag configurations.
These observations demonstrate that PP should possess a high melt strength (of at least 20 cN measured at the conditions used in the test) and a high zero shear viscosity so that its rate of sag will match the low level of sagging experienced with ABS.
We intend to use the demonstration site to allow European customers to understand firsthand the full value of this new technology for protection against voltage sags for their specific manufacturing operations.
amp;uot;Following an in-depth analysis of SMES, we believe that this product can significantly help increase our productivity and reliability by providing protection from voltage sags.
For almost two years now, American Superconductor's PQ VR has provided back up power for many substantial voltage sags," said Ron Coney, technology strategy manager at Eskom.
The foundry has been experiencing a significant number of plant shut downs owing to momentary sags in electrical voltage caused primarily by lightning storms typical in the region where the foundry is located.
